I’m not exactly sure why that is happening, hopefully @dae can answer / fix that. (I think this is the problem most users were having rather than the one I made a post about a few days ago, and it is extremely confusing as I cannot see a reason for it. see:
Error thread 1
Error thread 2
Error thread 3
However, as a tempory fix, you should be able to get around it by doing the following:
- Navigate to tools->add-ons
- Select the add-on and click ‘view files’
- Navigate to user_files/events.db
- Copy / move file to a temporary location (e.g desktop)
- Delete add-on and redownload the add-on (remember to restart Anki)
- Navigate to user_files once again and replace the new events.db file with the file copied / moved earlier.
- Restart anki and it should be working
