Answered Upgrade to Modx 2.2.6 - Manager Resource Tree Missing + Blank Pages

Hi, I'm hoping someone can help me out. I recently upgraded my live site from 2.1.3 to 2.2.6. I previously tested locally with upgrading from 2.1.3 to 2.2.5. This worked fine, so I proceeded to upgrade live using 2.2.6. Running mysql 5.0.96.

I updated all packages and cleared the cache (from manager) before updating, apart from accidently remaining logged in. (doh!)

The upgrade went fine apart from a couple of errors:
[2] => Duplicate column name 'is_stream'
[2] => Duplicate column name 'hide_trees'

Now when I log in to manager the resource tree is missing and any tabs I click present blank pages.

I had a search about and thought it could be cache and sessions due to not logging out. I couldn't flush sessions from manager so I manually cleared the cache by deleting the files and I deleted modx_session table entries. This did not work.

I then made sure cache was cleared and modx_session was cleared and uploaded the install files again and re-ran setup. This time there were no upgrade errors.

But there is still no Resource Tree and any think I click gives blank pages!!!

Please please help.

Thanks,

Dave
