403 error on my website

I hope someone can help me – I’m getting a 404 error on my site on certain pages.
I’ve had a look at the error log but not really sure what I’m looking for or what to do about it.

403 – Forbidden Error

You are not allowed to access this address.
If the error persists, please contact the website webmaster.

If you are the webmaster of this site please log in to Cpanel and check the Error Logs. You will find the exact reason for this error there.

Common reasons for this error are:
•Incorrect file/directory permissions: Below 644.
In order files to be read by the webserver, their permissions have to be equal or above 644. You can update file permissions with a FTP client or through cPanel’s File Manager.

•Restrictive Apache directives inside .htaccess file.
There are two Apache directives which can cause this error – ‘Deny from’ and ‘Options -Indexes’.

Here is a copy of the error log:
