I've successfully installed the modification, and have done so many, many times on client sites. This time, however, there is something wrong. After installing the mod and going to the PHPBB SEO tab in the admincp, I cannot save my changes to the settings. I can select my settings, and I can hit save. When I hit save, it says that the cache file was written successfully, but the settings aren't saved.
Additionally, phpbb_cache.php isn't in the cache directory like it is on my other sites that I've done this on.
I've verified that the cache folder is writable, and I'm just losing my head trying to figure this out. Here is the message the phpbb seo gives me on the "SEO Class Settings" page:
The cache folder configured is : e:\hosting\member\newsoftw\forum\phpbb_seo\cache/
The cache folder was successfully found.
The cache folder is writable.
