Thanks for the answer. Here are the mods installed :
1. Ad Managment 2.3
2. SMF 1.0.14 / 1.1.6 Update
3. Thumbnail Topic Mod 1.1
4. The Rules 1.06
5. Welcome Topic Mod 1.1
What kind of test or information may I provide here to go to a resolution ?
Up, is there any upgrade file I can use to try to update the DB ? I did not see any SQL file to apply when installing this mod ??
