Joomla 2.5.27 : White page after installing the upgrade 2.6.12 aio

[proxima]

Hi,
I have Joomla 2.5.27 Stable
From the official website virtuemart I downloaded the updates ...
then installing the com_virtuemart.2.6.12.tar.gz everything perfect!
after installing the file "aio - com_virtuemart.2.6.12_ext_aio.tar.gz" does not work anymore ... the site administrator side works tutto..il site from a blank page.
thanks so much

what version of php is your server running?
i have joomla 2.5.27 with virtuemart 2.0.8e and clicking the front end link shows a completely white page - no content at all.

i'm starting to wonder if it's the joomla template.

there are so many posts on here about debugging white screens - at a minimum it is expected that you first make the effort yourself to search for solutions...

And running such an old VM version it could even be the result of a visit from a hacker.....
