Yes I deleted all DB entries in member table, then unistall and reinstalled plugin.
‘Member’ table? Do you mean the WordPress Users and Usermeta tables?
And by ‘Uninstall’ do you really mean a full uninstall using the uninstall option of Simple:Press or do you mean deactivate and reactivate which are very different things?
I did anything on sfmember table but it seems to have only current users data.
So when on the User Groups listing (as per your screenshot above) if you click on the ‘Show’ button what does the listing actually show? 483 names or 12? If 483 then they must be in the sfmembers database table.
How I could resolve? I have a dozen of users right now since we are migrating from another forum, so I could make a backup of the table and delete all entries if It is needed
A proper and full uninstall of Simple:Press will remove all of the SP data if that is what you want to do.
