Could be the database coalition , it was iso-8859-1 prior to 7.6.0 but today it is utf8 .
If you changed the database from iso-8859-1 to utf8 either by the upgrade or fat finger.
Then the character set may not be supported.
It is a conversion step that is needed in the mysql database.
You can check it with like phpmyadmin.
It will show either latin 1 or utf8 per table.
It should be global across all of them.
Todays standard is utf8 for every forum package i have seen.
