Title: Blank white screen when looking at Orders......
Post by: cwbalmer on September 24, 2015, 11:30:24 AM
Hi all,

Strange one here, but I have just exported an entire Joomla (v2.5.20) website and its contents to another server using the Akeeba backup and restore functions.

all is well and VM is running fine EXCEPT when I click on Orders to see whats in there, all I get is a white screen with no content at all. I have to hit the browser back button and can then see everything as usual.

Everything like Products and Categories in VM can be viewed fine..

Has anyone seen this problem before?

Thanks in advance for any hints!

Sounds like a php resource issue. Turn on VMdebug to see the error.

Or ask your host where your php error logs are to be found and post any fatal errors you find here

What has appeared at the top of the screen now is:

Notice: Undefined variable: content in /home4/xxxchnaged/public_html/Live/GM/plugins/system/install/install.php on line 140

Notice: Trying to get property of non-object in /home4/xxxchnaged/public_html/Live/GM/plugins/system/install/install.php on line 36

Looking at these 2 lines

Line 140 - return json_decode($content);

Line 36 - if($content->error == '1' && JFolder::exists(JPATH_ROOT .DS. 'components' .DS. 'com_devn_vmattribute'))

I just cant see why these have suddenly appeared!!

1. they are just notices so won't cause a fatal error

2. they come from something called VM Design Tools  - never heard of it

3. there is no such plugin as "system/install" on any of my VM's

Yeah I suspected they were only warnings - they seem to come and go...

the white screen issue was happening before these 2 erroneous messages appeared.... and is still here...

Frustrating!!

Or ask your host where your php error logs are to be found and post any fatal errors you find here

or you can trying guessing the error..  ;)

And if in doubt search thir forum for "hostgator"  over the last 12 months. Too many people have problems with that host.

To be fair I've used them for about 4 years and they've been really good. The odd issue true but nothing major....

Seom error logs I am seeing are as below:

[Thu Sep 24 10:36:12 2015] [error] [client 86.179.153.2] File does not exist: /home4/cwbalmer/public_html/Live/GM/administrator/components/com_fsf, referer: http://www.cwbconsultancy.com/Live/GM/administrator/index.php?option=com_virtuemart&view=config
[Thu Sep 24 10:35:32 2015] [error] [client 86.179.153.2] File does not exist: /home4/cwbalmer/public_html/Live/GM/administrator/components/com_fsf, referer: http://www.cwbconsultancy.com/Live/GM/administrator/index.php?option=com_config
doesnt seem very helpful tbh!

OR could it be that the site has 2 references - www.gm-supplies.co.uk and  /home4/cwbalmer/public_html/Live/GM/ ?

make sure no $live_site is set in configuration.php
Title: Re: Blank white screen when looking at Orders......
Post by: cwbalmer on September 24, 2015, 21:09:48 PM

Yup that is the freestyle FAQS plugin - which is disabled anyway...

Hmmm..
