Whenever I try to update my Permalink settings or use the Theme Editor to modify some file, I am redirected to a 404 page. This also happens when I update the All-In-One SEO Pack plugin's settings. This does not happen in the case of other settings pages or plugin options. I have tried re-uploading WordPress from a fresh local copy, and have also tried deactivating all plugins. My hosting provider has given up, blaming WordPress. What is wrong here?
Some things I suspect:
.htaccessfile. I am not using anything extra, other than turning off
- Suhosin. After a recent security breach, my provider recompiled PHP with Suhosin. I have disabled it currently, which solved a lot of compatibility problems with other plugins.
- File/folder permissions.
- PHP memory issues, maybe?
