Project file changes causing `SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1' for key 'PRIMARY'`
As far as I know the craft_info table should only have one row.

This would mean that either:


You have something installed / configured wrongly somewhere causing it to insert a 2nd row into the table
Or it's actually a craft bug, I'd advise you to search through The CraftCMS Github Issues and check if there's any issue resembling yours, if not create an issue there so it gets solved in the next few updates.
