Site dies stops working

  • For some weeks now I have been experiencing major problems with my website https://www.epnet.co.za I get a site error 500 no other information. I run WordPress on a Windows Server 2008 and this problem is easily rectified if I re-install WordPress. So I have counted out plugins, themes etc as by replacing WordPress it all works very well indeed – until the next day when I have to do this all over again. I cannot see what the issue is however I am working on the premise that it is some malicious code but do not even know where to start looking? I have looked at most of the WP pages and cannot see anything however it could be a Javascript somewhere but cannot figure it out? I am running Anti Malware software all day long but it does not pickup anything and am at a loss. Has anyone any ideas?

    Internal server errors (error 500) are often caused by plugin or theme function conflicts, so if you have access to your admin panel, try deactivating all plugins. If you don’t have access to your admin panel, try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

    If that does not resolve the issue, try switching to the Twenty Fourteen theme to rule-out a theme-specific issue. If you don’t have access to your admin panel, access your server via FTP or SFTP, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue.

    If that does not resolve the issue, it’s possible that a .htaccess rule could be the source of the problem. To check for this, access your server via FTP or SFTP and rename the .htaccess file. If you can’t find a .htaccess file, make sure that you have set your FTP or SFTP client to view invisible files.

    If you weren’t able to resolve the issue by either resetting your plugins and theme or renaming your .htaccess file, we may be able to help, but we’ll need a more detailed error message. Internal server errors are usually described in more detail in the server error log. If you have access to your server error log, generate the error again, note the date and time, then immediately check your server error log for any errors that occurred during that time period. If you don’t have access to your server error log, ask your hosting provider to look for you.

    Dear James
    Many thanks for your time but these are all the standard things that we have already done without result..
    We have isolated our issue to something in the WordPress Includes folder. We will be going through all the files there in particular looking into the JS files.

    To trace an issue in the Includes folder we will use the old fashioned method of replacing them one by one and update and test each time.

    The website in its current state has been working for months without a hitch, updating only the WordPress each time.

    Regards
    Gordon

    Ok, so please move on to the last paragraph above, the one about providing exact errors from your server error log.
