"Warning: Duplicate entry" errors - getting lots of them

are u using only the core modules, or any non-core modules, or any 3rd party modules?

It would definitely help to post a dozen of those error messages, the first ones, and also to describe one specific case where this happens, what is the URL, what you are doing etc. That could help locate the problem.

Yeah, well reading the error is the first step in diagnosis - so knowing what table was being accessed at the time and the query involved would be sorta invaluable.
Just one or two lines would be enough...

In general - with the paucity of information available - "duplicate entry" is usually a symptom of the 'sequences' table getting out of sync - which is usually caused by partial migrations or unsyncronized restores from backups.

I seem to be getting the same duplicate entry errors, lots of them.

I just updated a bunch of modules and ran update.php. I get 42 pages of "user warning: duplicate entry...."

here's the first few... The site seems to work OK despite all the warnings. Should I just ignore them?
