Some background:

I setup six blogs this week, all using Wordpress 2.92, installed with Fantastico on a baby croc plan with Hostgator.

I used the same theme (heatmap 2.5.4) and plugins for each blog.

They were all up and running, no issues at all.

I go to create a new blog this morning, using the same setup, and when I try to change the theme settings, I get the following error:

Forbidden

You don't have permission to access /wp-admin/themes.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8n DAV/2 mod_fcgid/2.3.5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at http://www.mydomain.com Port 80

I tried uninstalling WP and doing a clean install, still the same issue with a clean installation.

So I went back and checked the six other blogs that I had setup over the last week or so, and they are also now giving me 403 or 404 errors when trying to change theme settings, and everytime there's an error it points to either themes.php or functions.php

At this point I'm at my wits end trying to figure out what the problem is. Hostgator support looked at it and thought maybe it was a permissions issue but they reset those and I'm still having the problem.

At first I thought the problem might have been related to a plugin I recently installed on the previous six blogs that morning (ByREV Fix Missed Shedule Plugin) to deal with a missed schedule bug with WP 2.92, and that maybe that had mucked things up. But then I checked a blog I built months ago, also using the same theme and plugins, and now it too is also encountering the same problem.

Any ideas? I tried deleting my htaccess, uploading a blank one, uploading one with this snippet I found on the hostgator forum:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Nothing has worked. I still get 403 or 404 errors everytime. Everything was working perfectly yesterday so I know this setup DOES WORK, I've just mucked something up somewhere and I'm clueless what it is.

I read a related thread here and tried chmoding the wp-content folder to 0755 and still having the issue.

Any thoughts? Thanks!
