The main Drupal config index page won’t load. In all browsers, it thinks for a couple of minutes, then spits out an internal server error. It is only “/admin/config”. However, sub-pages of config, like, “/admin/config/development” are ok! Content pages all work ok, modules, reports, appearance etc. all work ok.
The sever log says: Script timed out before returning headers: index.php
I had added a module or two and removed them that day, but nothing to core or any .htaccess files.
Any hints at what is wrong with this page? Any ideas welcome, thanks!
