I'm glad you found a solution. If you don't need/want that setting enabled, you should be good to go.
If you want to re-enable it, you need to make sure you rename the htaccess.txt file to .htaccess. If you made any alterations to the .htaccess file, that could also cause problems.. so I'd undo those as a test as well.
I hope that all helps, but if you need more help or have any other questions, just let me know.
Thanks,
Alex
