Website blank after upgrading Virtue in version 3.4.1 or 3.4.2

[DadoO]

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

[GJC Web Design]

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

[DadoO]

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 ?

[ritchy]

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

[GJC Web Design]

perhaps try switching off the VM 404 error handling in VM config as this may be causing a loop
