Hi,

I use K2 on a fresh Joomla 3.4.0 installation. Each time I try to access a blog entry, I do get an empty page displayed (no errors show). Turning on Joomla error reporting to maximum, I do get:

---
Fatal error: Cannot redeclare treerecurse() (previously declared in /Applications/MAMP/htdocs/mysite.com/templates/envor/html/mod_k2_tools/categories.php:15) in /Applications/MAMP/htdocs/mysite.com/templates/envor/html/mod_k2_tools/categories.php on line 133
---

System information
Joomla! 3.4.0 Stable [ Ember ]
K2 v2.6.9
PHP Version 5.6.2
Joomla Platform 13.1.0 Stable [ Curiosity ]

Anyone an idea what the issue might be?

Many thanks

Hello,
This is a template issue.
The treerecurse() function is not a part of the default module.

Krikor - I'm having the same issue and was wondering what to do to correct it. You mentioned it's a template issue, and that treerecurese() function is not part of the default module. Is there an admin template that does work?

Is this issue happening on the backend?

The error axxo was having was caused in the frontend.

Yes. When I click to edit or create a K2 document I get a blank screen. I recently upgraded to Joomla 3.4.0. I have also tried reinstalling the latest K2 and it's still occurring.

Issue Resolved: Somehow when I upgraded to 3.4.0 it turned on User Registrations and I had 30,000+ bogus users that had signed up. I deleted all the users and now K2 is working properly. There may still be a problem with sites that have alot of legitimate users. I'm thinking the problem is that K2 is trying to load all those users into the drop down menu and it's crashing. Might be a good idea to set some sort of record limit to prevent this on other sites.

Enable error reporting from your site's Global Configuration to see the actual error.
