I use the Panda Theme and updated from 1.6.1.1 to 1.6.1.9. Everything worked fine except for getting a error message from the update.php script. 34: Internal SQL error. After executing again I got 28. So I had a look at the backend and it was 1.6.1.9. So it kind of worked.
All content was still there and all configuration and theme customization was in place. Except for, some hooks weren't displaying. And I couldn't figure out, how to display them. Changing template to trigger the hook installation messes up everything.
What do I need to do, to makes this works. It's just very little that needs to be displayed and everything would work .
