403 forbidden error in yopur site- You don’t have permission to access

If you are running a blog or any dynamic site then please check on your plugins which are you using and see the plugins which you should not use if you are a  shared hosting user.

In general 403 Forbidden HTTP status code defines that the client was able to communicate with the server, but the server won’t let the client access what was requested.

This response is returned by the Apache web server when directory listings have been turned off. Microsoft IIS responds in the same way when directory listings are denied.

hOW to fix this problem :

check the .htaccess file (do not change anything just look on your other blogs or search on internet for the coreect one). If you want to make changes then please upload the file i mean backup first

last option is to mail the hosting provider.
