style & plugin upload problem (vb 3.7.2)

[netsavy006]

I'm using vbulletin 3.7.2. When I try to upload a style I get this message:

An appropriate representation of the requested resource /admincp/template.php could not be found on this server.

I went and downloaded vbulletin 3.7.2 again and uploaded the file fresh but still get this message.

Here's my forum link if it helps:

Have you checked your FTP to make sure the file exists?

I reinstalled vbulletin 3.7.2 and checked and the file is there but I still get the error.

Also when I try to install a plugin I get this message:

An appropriate representation of the requested resource /admincp/plugin.php could not be found on this server

I just checked and the files exist on the server.

If that scan comes out clean, it is probably because of incorrect server configuration. Ask your host in that case.

I found in another thread on another forum about adding this entry:

SecFilterEngine Off
SecFilterScanPOST Off

After adding that to .htaccess I now get this message when trying to upload a style:
"No file uploaded and no local file found."

Suhosin
Module Loaded Yes
Results
Suhosin can limit the amount of data submitted and encrypt cookies causing problems with several aspects of vBulletin.

mod_security
AJAX Unicode Issue No
Results
The above setting will indicate if mod_security is preventing some AJAX requests from being submitted to vBulletin. If this shows Yes then you either need to disable mod_security or change the AJAX settings with the vBulletin Options and disable Problematic features.
