2.0.22a to 2.6.10 Upgrade gives blank page

[bubberz]

We just upgraded our test area from 2.0.22a to 2.6.10 and all VM links give blank pages.
I've got reporting to maximum
I have nothing in the log directory, so nothing is showing up
SEF is turned off
PHP is 5.3

I followed the instructions to unzip the 2.6.10 file and install both main files.

Please advise.

Just test .. Change the template to a standard.

Exactly which PHP 5.3 version?  Minimum for current VM versions is PHP 5.3.10 and recommended is PHP 5.4+

Enable vmdebug. See http://forum.virtuemart.net/index.php?topic=121692

[bubberz]

Our version is PHP 5.3.28

Tried changing default template to:
Beez2 - Parks Site & Beez2 Default templates...white screen for categories links.

Please advise.

Standard white screen debugging .. plenty of posts on here about it - basically look in the logs, set debugging on, reporting on full, ask the host etc etc
white screens are normally a fatal php error or you've run out of memory on the server

White screen for categories? Are you using old menu links to "categories" or to "category"?

[bubberz]

Hi!
I just created a new menu item of type VM Categories Layout, and that's a white screen too.

As noted before:
Error Reporting is Max
SEF is turned off
PHP 5.3.28

Please advise...thank you!

The view "categories" is outdated. Please use the view "category"!

Hi Milbo!

Only menu item type options I have under VirtueMart are these, and I did the 2nd one:
VirtueMart Shopping Cart
VirtueMart Categories Layout
Category Layout
VirtueMart Manufacturer Default Layout
VirtueMart Manufacturer Details Layout
List Orders
VirtueMart Product Details Layout
VirtueMart Account Maintenance
User Edit Address Displays
vendor contact Displays
vendors Displays
vendor details
View vendor TOS
VirtueMart Front page

Which one are you referring to?

Thank you!

Which one are you referring to?

"VirtueMart Categories Layout" is obsolete
"Category Layout" should work

[bubberz]

Just tried that...white screen again

Please advise

[jenkinhill]

Turn on VM debug. There must be an error message if you have a WSOD.

"VirtueMart Categories Layout" is not a menu option now. The list from 2.6.10c is in the pic:

[attachment cleanup by admin]

Hi everyone...well, I don't know what flag got flipped, but turning the VM debugging on got rid of the white screen.
All debugging is off now, and the site is working.

Resolution >> turn debugging in VM on, refresh page...all was good...turn debugging off...refresh page...links are good to go.

Thank you for your help!

Sounds like a cache problem at the end, not recognising the new menu link.

Or it is a single save of the VM admin - I'm sure I've seen this before myself
upgrade - all sorts of bollocks fire off - dead links, white screens -

Go into panic mode - check logs - turn on J debug and reporting - remember VM debug - switch it on - all comes right - switch it off - still alright..

Maybe a single save of the VM config is needed after a update from early versions?
