Hello,  
I have deleted a test project with historical tag.  
The link to the data base is deleted.  
All the tags use in the project are also deleted.  
However there is this alerte in the log :

If someone know a solution?  
Thanks.

Delete the tag (or tags).

Tags aren’t part of projects, so aren’t deleted when you delete the project that used them.

Thank for your reply but I have already deleted all the tags in the Tag Browser, from an other open Designer project.

Did you delete the datasource while store-and-forward records were quarantined? That would make a mess. You might want to get IA support involved.

Ok. You most certainly want IA support involved. Something is stuck in your internal DB, I think.
