Another V2.6 update that has ruined my site! Help!

[ucanfixit]

I am running joomla 2.5.20 and VM 2.6... PHP 5.3.24 I updated from the previous version through the extenstions manager.... Now my home page is blank!

The rest of the site works fine but my homepage wont display!!! Help please!

I turn on the Virtumart Debug messages and see "Fatal error: Class 'vmRequest' not found in /home/content/51/7550951/html/plugins/vmcustom/specification/specification.php on line 98"

on my homepage.

I HAVE NO CLUE WHERE TO START FIXING THIS!!!

Also now that I turn on debugging in my Virtumart admin I see these errors:

vmdebug $siteLang: en-GB self::$_jpConfig->lang en_gb
vmdebug vmTime: loadConfig db no: 0.00405192375183105

vmdebug vmTime: VirtueMartControllerVirtuemart Finished task virtuemart: 0.377852916717529
vmdebug End used Ram 4.5M
vmdebug Peak memory peak 4.5M

And at the TOP of my joomal page in the ADMIN I see:

Notice: Undefined offset: 0 in /home/content/51/7550951/html/plugins/system/jo_vm_socialshare/jo_vm_socialshare.php on line 26

HELP!!!

Thanks in advance!

UPDATE: I disabled the plugin called "VMCustom - specification" and how the homepage loads fine.

Any idea why this happened and what I can do to fix it plugin? It must be for something

Did you also install/update the aio component?

Have a look at http://forum.virtuemart.net/index.php?topic=123237.

So - a test..

Clean J2.5.20 - Vm2.0.26d & AIO same

Live update to VM2.6.0 via the VM live updater

Runs fine and finishes with

Checking VirtueMart modules...Installing VirtueMart Administrator modules
VirtueMart2 modules already installed
VirtueMart2 pdf moved to the joomla libraries folder
Installing VirtueMart Plugins and modules Success.

You may directly uninstall this component. Your plugins will remain. But we advice to keep the AIO installer for updating

on administrator/index.php?option=com_virtuemart&view=liveupdate&task=install

White screen on frontend with fatal error (in logs) of

PHP Fatal error:  Class 'vRequest' not found in /home/xxxxxx/public_html/vm2t4/plugins/vmcustom/specification/specification.php on line 98

Backend:  administrator/index.php?option=com_virtuemart_allinone

no xmap etc as reported in some posts

So would appear something is wrong with the installer: the plugins/vmcustom/specification/specification.php is the latest - i.e AIO has installed - all files in plugins and modules are new (afaik it's new for 2.6.0?)

Trying to update again from LIVEUPDATE_REFRESH_INFO  results in no change

Looking in the admin helpers folder on the server there are indeed 4 files missing - see screen shot


Even after logging in and out - cache clearing - refreshing the live updater is still reporting  the old VM version

A new version is available

Before you update your live system, please test the update on a backup system in order to prevent loss of data. Expect small incompatibilities, if you are using 3rd party extensions or your own customizations (plugins, modules, templates).
Remember to update also your plugins and modules, for which you may use the live updater in the VirtueMart-AIO installer.

It really seems the Live Updater updates the AIO but NOT the VM component

file times on VM mods and plugins ->12:18

file times on VM comp:  ->  12:06 (when I updated to 2.0.26d prior to starting this test)

Then tried a manual install of 2.6.0 thru Joomla installer

Successful!

All errors gone - comp updated -   Live update reports correct version

CONCLUSION:

The Live Updater is ONLY updating the AIO - this is the source of these multiple white screens with PHP Fatal error:  Class 'vRequest' not found in /home/gjcwebde/public_html/vm2t4/plugins/vmcustom/specification/specification.php on line 98

It isn't reporting the failure at all and appears to have worked

SOLUTION:

Don't use the Live Updater (I personally never do - have always had problems with it) - use the Joomla installer

If you have a white screen and trace the error as PHP Fatal error:  Class 'vRequest' not found in /home/gjcwebde/public_html/vm2t4/plugins/vmcustom/specification/specification.php on line 98 then re-install JUST the com_virtuemart.2.6.0.zip  from
http://dev.virtuemart.net/attachments/download/698/com_virtuemart.2.6.0_extract_first.zip

SOLUTION:

Don't use the Live Updater (I personally never do - have always had problems with it) - use the Joomla installer

I also have never used it despite hundreds of VM updates - I always use Joomla's extensions installer.
