Hi - I hope someone can help me or at least give me some clues about the problem I'm having.
A couple of weeks ago I upgraded a WP install from 2.2.2 to 2.5.1, and discovered that every time I try to edit an already existing post or page, I get a 500 Internal Server Error (on the page `/wp-admin/post.php?action=edit&post=3&message=1&_wp_original_http_referer=
http%3A%2F%2Fdomain.org.uk%2Fwp-admin%2Fedit.php`) although when I go back and check, the changes I make have actually saved. I wondered if it was a problem because of the upgrade and deactivated all my plugins, but I wasn't able to solve it. However, it's only a testing site, so I wasn't too worried.
Today I did a brand shiny new clean install of 2.5.1 on a brand shiny new hosting account - no plugins, nothing already existing except for the default first post and about page that WP includes. But again, if I try to edit the existing post or page, I get the 500 error. My error logs tell me nothing more helpful than
[error] File does not exist: /home/hastwell/public_html/500.shtml, referer: http://domain.org.uk/wp-admin/page.php?action=edit&post=2
This isn't so much of a problem for me since I know that the edits are actually saving, but I can't set up a site for a client with this happening. Anyway, the server I have it on is running the following:
Apache version 2.2.6 (Unix)
PHP version 5.2.5
MySQL version 5.0.45-community
Any ideas, anyone? Thanks in advance!
