New Modules Not Listed at admin/build/modules So I'm trying to install the Backup and Migrate module on an older drupal site (still 6.22) but it, or any other module, wont show up on the list of modules at admin/build/modules.  The current modules (active and not active) show up, but nothing new will.

All files and sub-folders have the same permissions and owner of the new modules, also tried flushing all caches.

What else could cause this?
Check the following:


Are the uploaded modules correctly unpacked? No .tar or .zip endings?
Does the problematic module contain its .info file and are you sure the module is D6 compatible?
Is the module placed into the correct folder where you keep all contributed modules?
