I've been on http://300mclub.org/ for years and years. Recently I am getting a 403 forbidden error. They're recently had complete software changeover (i.e. pretty much since the last time I logged in). They are insisting it has nothing to do with this. They have double checked my IP and insist that nothing on their end is blocking me. They want me to contact my ISP. I'm trying to tell them that there is no question that it is their system actually throwing up the 403 page, and the only entity in the universe that knows why is their server logic. Somewhere in their code, my request is failing a condition, causing it to branch to an error - it's just not telling them why. My question: is there any conceivable way that the problem is on my end - whether my IP, or my ISP or whatever? Here is the content of their error page: 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'.
