Strange error when searching templates

[LaPiba]

Hi,

I am running vBulletin 3.8.5 . When I enter Control Panel --> Search Templates, if i do a search for the following string:

><

I receive a "forbidden" error: "You don't have permission to access /..... /template.php on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."

All other searches I did, worked. This particular one returns the above error.

Is this a bug?
Thank you for your help.

You'll need to speak to your host regarding this. It's possibly a mod_security issue which they will be able to resolve for you.
