After upgrading my Drupal to 6.8 I faced the problem that one module didn’t work right. Maybe it was broken before and I simply didn’t notice that beforehand. However I needed to fix the tables and re-installing the module seemed the best idea to me somehow.
What you need to do are the following steps:
- Deactivate you module
- Use the uninstall tab on the modules page
- Remove the module from sites/all/modules/
- For re-installation delete all corresponding entries from the “`variable”` and
systemtables (I think you have to do that for all site’s tables on a multi-site installtion)
- Run “`update.php”` just to make sure
- Upack the module again
- Run “`update.php”` again
That worked fine for me at least.
