It seems ok ?
Please, comment or delete those lines (106 and 107). It's to test if you can enable the addon.
Remember, after deleting those lines, disable and reenable the addon.
By commenting these lines, I can still enable or disable the addon in "project settings". Nothing has changed.
Attached is the error message when deactivate addon :
Is it possible to see (picture) how this button labeled "database" looks like?
A picture of this button ?
At the top right of the screen, just below the close button. I'm really sorry for the late answer.
