I apologise if this has been posted before - I just know how frustrating it was to find a fix for it when I first came across this problem, so I've decided to post it here so it is readily available.

For some reason, when installing new themes, MyBB's inline moderation tends to break and displays this error on use:

Quote:Sorry, but you did not select any threads to perform inline moderation on, or your previous moderation session has expired (Automatically after 1 hour of inactivity). Please select some threads and try again.

This is easily solved by doing the following:

1. Log into your MyBB admin control panel.
   
2. On the left side, you should see a category called "Quick Access", in that category, click the "Templates" button.

6. Once found, click options and select "Full Edit"
   
7. Scroll down to line 74, press Enter to add a new line and add the following:
