"An import is currently in progress. If you are returning to continue the import, click the button below to continue where you left off."
Now the issue is, something broke a long time ago with an import, apparently. The reason is my board has been running fine for over a year and a half, and if I tell it to continue the import, it wipes out my forum and starts to import my old data all over again - and I end up having to restore the entire site datebase from backup. I have no idea which import, and when, might have caused this as it's been a long, long time... and as noted my board has been operating fine (1.7 million posts, etc).
This error message is stopping me from installing an addon which later does an import. How do I manually remove this message, is there a mysql query I can run to do tell it the import in progress no longer exists?
