We're back in business. Up and running on the dev version. Thank you for your help!
I am still having that debug output error though. Thought it was fixed but it's not.
Like I wrote that error only occurs if:
a. the debug output path doesn't exist
or
b. Hybrid isn't allowed to write into it
=> check your settings.
Cu Selur
Had to uninstall and reinstall to get the debug path working properly again. No clue what was causing the problem.
