WordPress MU

Just installed 2.84

I get these errors when trying to edit a blog's setup:

Firefox: An appropriate representation of the requested resource /reports/wp-admin/wpmu-edit.php could not be found on this server.

IE: HTTP 406

So I checked and the file IS THERE. I deleted it and uploaded it again, but I still get the error. The file is 19.42 kb.

Any clues?

Check your permissions. Try setting it to 755

Thanks, tried that, but still no go.

Also, I installed MU on two different domains and it's the same problem with both.

I just searched for "wpmu-edit.php" and it seems like others had this problem 2 years ago and a year ago, and there are references to making changes in tables.

Seems like I shouldn't be the only person to have this problem if everybody's tables aren't set up right.

Have you got mod_security enabled?

If so have you got the following in your .htaccess file:

<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>

I don't know whether mod_security is enabled, have a managed server and have to ask support.

This is my htaccess:

RewriteEngine On
RewriteBase /reports/

#uploaded files
RewriteRule ^(.*/)?files/$ index.php [L]
RewriteCond %{REQUEST_URI} !.*wp-content/plugins.*
RewriteRule ^(.*/)?files/(.*) wp-content/blogs.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteCond %{REQUEST_URI} ^.*/wp-admin$
RewriteRule ^(.+)$ $1/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>

ANd I just looked at my error log and this is all I get:

File does not exist: /home/liars/public_html/406.shtml, referer: http://liarsandcheats.info/reports/wp-admin/wpmu-blogs.php?action=editblog&id=2

Is there anything else to check in Cpanel?

The 406.shtml is a file that mod_security is trying to display, so it looks very much like a mod_security issue.

Thanks, I opened a support ticket for my server and will update here.

Thanks all for your help, it was a server issue and they fixed it.
