I've uploaded the following Plugins:
All In One SEO
Get The Image
Hits IE6 PNG Fix
Top Level Categories
As you can see, that's not a massive amount, but what happens is that when uploaded and activated, on the Dashboard the WP News and Plugins drops downs don't load. I can live with that...although it points towards an error.
However, what's crucial is that NextGen won't produce thumbnails due to a 500 internal error and I've tried to upload WP-Events and cForms but when I activate one of them I get the 500 Internal Error.
Can anyone help me please? I deactivated all my plugins and then found I could active cForms (for example). So it's as if it has something to do with too many plugins or a conflict? My PHP Memory is 40MB and I'm using MySQL 5.
