Hello everybody
I have a strange problems
I have placed the latest version of Virtuemart, so 3.4.1 and after one day the second upgrade 3.4.2
A strange problems occurs after only 8 or 12 hours !!!!
Web site out, blank page ...
ONLY with a php 7.2.10
When I have placed Virtuemart 3.4 with php 7.2.10 there's absolute no problems
Now for Virtuemart 3.4.1 3.4.2 i could only works with php 7.1.22
A bad script?
Commands not accepted with php 7.2.10 ?
Bad memory emptying, dump ?.
I'll don't know
Have U got an idea ? For this occurs ONLY after upgrading in 3.4.1 or 3.4.2
my config is actually :

Check your error log and if you do not finf any usable error code. Revert back to php 7.1.2. Are you using custom template.This could be a issue with either VM, a plugin or template changes.

It's a shorcut of the list (I have 3000 products on my shop)

If I place php 7.1.22 no one errors
What sort of problem is ??? For I don't know for an issue
have u set your memory limits etc correctly for php7.2?
Normally in Cloud Linux etc u need to set memory, max vars etc etc per php version
should imho be 256MB at least
I have seen 128 MB, so I have modified the ini to 256 now
It's a dedicated server not cloud etc ...
Same problem today with php 7.1.22
I haven't this problem before upgrading to 3.4.1 or 3.4.2
It's strange
I have seen an old post with the same problem in April 2018
https://forum.virtuemart.net/index.php?topic=136025.0
Perhaps same condition ?
So. I also have the same problem after updating from 3.4.0 to 3.4.1 also on 3.4.2. Blank page but only after logging in to e-shop. Main page of e-shop and others report error: 0 - Class 'JToolBarHelper' not found
I deleted all temporary files. Updated and reviewed tables. Nothing helps.
If I go back and rewrite Virtuemart to version 3.4.0, everything works correctly.
PHP built Linux cybers-1-web-01 3.2.0-4-amd64 #1 SMP Debian 3.2.82-1 x86_64

Download it from http://dev.virtuemart.net/projects/virtuemart/files and reinstall older version

Same issues here after the 3.4.2 update, although only some pages are blank and I also get the 0 - Class 'JToolBarHelper' not found. However in my case the worst issue is that the CPU usage on my VPS is going crazy (up to 200%) and it's only the mysql process, all other processes are normal below 5%. This did not happen with version 3.4.0. Is there a way to roll back to 3.4.0 without having a backup? like just install it over 3.4.2? right now I have to restart the mysql server 20 times per day for the server not to crash.
I'm using php 7.2.10, mariadb 10.1.36 and joomla 3.8.13 by the way
perhaps try switching off the VM 404 error handling in VM config as this may be causing a loop

See: https://github.com/joomla/joomla-cms/issues/14330
Also perhaps this might be related: https://issues.joomla.org/tracker/joomla-cms/21960++++ mod edit +++++++++
ignore above - has nothing to do with anything
I included the class JToolbarHelper in Joomla frontend which solved that part of the problem (this is not needed in VM 3.4.0)
Quoteif(!class_exists('JToolbarHelper')) {
require_once JPATH_ADMINISTRATOR . '/includes/toolbar.php';
}
I also tried disabling VM 404 error handling in VM config but the CPU usage on my VPS is still maxed out on the mysql process. I rolled back to Virtuemart 3.4.0 for now until we can figure this out and the CPU usage on mysql went down to normal (below 2%).

I have do the same
Now working fine in old version 3.4.0 with Joomla 3.8.13
No news about this problem ?
A new version ? A file correction ?
How can the dev team fix something that has never occurred to them during testing or live and seems specific to certain installs?
All releases are extensively tested on the installs and setups available to them
I have all my installs (50+) running on J3.8.13, VM3.4.2 and php 7.2 with so far no reported problems
So you could setup a clone of your current install, install 3.4.2 and then find and fully report the error logging etc to give some clue as to whats happening. - an hours work at most..
as I read the post about JToolBarHelper -- it is some extensions using JToolBarHelper instead of JToolbarHelper ?

I don't think the JToolbarHelper class is the key to this problem, it's probably just a side effect of something else. As I said I included it in Joomla frontend and the error message disappeared but there was still blank pages and a massive CPU load on the mysql process. As far as I could see there was many queries opened by virtuemart_product in the database which didn't seem to close.
Anyway, hopefully next week I will have time to set up a clone and do some more testing. I am running a pretty standard setup with a commonly used template which is up to date. I do have customfields for all plugin v. 3.1.3 installed if that could be the culprit, but I'm pretty sure I tried to unpublish it without results.
Edit: I forgot to mention that when I included the JToolBarHelper class it did fix one thing, editing a product from the frontend started working instead of generating a 404 which it did without the JToolBarHelper class included. Again this worked fine in 3.4.0 without including JToolBarHelper. Maybe this can shed some more light on the issue.
This may only serve to confuse but out of all my upgrades one this morning threw a fatal that is to do with the new 404 handling by VM introduced in 3.4.2
It is the loop reported somewhere else here
this repeats 256 times
components/com_virtuemart/views/category/view.html.php(683): VirtuemartViewCategory->display()
components/com_virtuemart/views/category/view.html.php(322): VirtuemartViewCategory->handle404()
components/com_virtuemart/views/category/view.html.php(683): VirtuemartViewCategory->display()
components/com_virtuemart/views/category/view.html.php(322): VirtuemartViewCategory->handle404()
VM3.2.4, J3.8.13, php7.2.9 - VM Error handling 404 on - full SEF
But think unlikely to be connected with any reports of high sql usage
Short term fix from Stan (Rupostel) here:
http://forum.virtuemart.net/index.php?topic=141213.0
Hello,

Hello everyone!
Thanks for the development and updates!
After upgrading to version 3.4.2, a problem was found.
1) When you click on the edit button for any product through the frontend, a blank page and an error appears: HTTP ERROR 500
PHP 7.2 version, Jooma 3.8.13
When working with version 3.4.0, this error did not occur.
Please help me solve the problem.
Must we repeat ourselves every time?
Without the error NO ONE can help you!
http://forum.virtuemart.net/index.php?topic=121692.0
Sorry, but I very rarely visit the forum to know all these nuances at once. Thanks now I will know about it!
When I turned on the debug mode in VirtualMart, then when I clicked on the edit button, the following error was displayed:
# 0 Class 'JToolBarHelper' not found
Tell me, please, what next to do?
P.S. The advice of renaming JToolBarHelper in JToolbarHelper did not help.
Class 'JToolBarHelper' not found
JToolBarHelper is WRONG... you have to find the instance of that and change to 'JToolbarHelper'
if u have done this and the class is still not incl. you need to add this to what ever file is throwing that error
if(!class_exists('JToolbarHelper')) {
require_once JPATH_ADMINISTRATOR . '/includes/toolbar.php';
}
you need to find the file by Joomla debug on and/or xdebug on your server to get the path or search logging

As a quick-fix workaround you could add the code to your template (/templates/your_template/index.php)
if(!class_exists('JToolbarHelper')) {
require_once JPATH_ADMINISTRATOR . '/includes/toolbar.php';
}But the more proper way of doing it would be as GJC suggested, putting it in the exact file that needs it.
For example in joomla admin this class is already included in the /administrator/index.php file but not in the joomla front-end index.php. Perhaps this has something to do with security, I'm not sure, and I'm still uncertain what changed between VM 3.4.0 and 3.4.1/3.4.2 to cause this class to be missing.
Thank you for participating, vep87895!
But after all, most likely the problem is not in some external files, but in the changed VirtueMart. With version 3.4.0 under the same conditions it works correctly.
can u try this on VM3.4.2
file administrator\components\com_virtuemart\helpers\vmdefines.php ~ line 162
uncomment
//JLoader::register('JToolBarHelper', JPATH_ADMINISTRATOR.'/includes/toolbar.php');
remove the slashes
I believe JJK is correct, the issue is a VM issue related to:
https://github.com/joomla/joomla-cms/issues/14330
The class' correct cased name is JToolbarHelper, not JToolBarHelper, and has been such since 3.0.0 (same applies to all JToolbar* classes). The casing is important with our autoloader because it will split the class name based on CamelCasing if it needs to try and load a file that hasn't yet been loaded.
JToolBarHelper will try to find a file at libraries/(cms|joomla|legacy)/tool/bar/helper.php whereas JToolbarHelper will use libraries/(cms|joomla|legacy)/toolbar/helper.php.
a non Joomla issue but an issue with using incorrect CamelCasing for Joomla 3+ when calling the JToolbarHelper

That is the answer and solved the error. I only experienced the error when editing a product from the frontend.
Good .. no doubt fixed in the next release
Yes, after correction editing worked correctly!
Very grateful to you, GJC Web Design, for the solution found!
BTW - this
QuoteJToolBarHelper is WRONG... you have to find the instance of that and change to 'JToolbarHelper'
this is complete rubbish .. lead up the garden path ( and terrible things done to me once we got there) by this:
https://github.com/joomla/joomla-cms/issues/14330
ignore .. the class is registered as JToolBarHelper in VM and Joomla
