Page isn’t working. Currently unable to handle this Request. HTTP ERROR 500

Question:

I have recently inherited this webpage account for our club. When I go to log into the webpage admin section it displays the following error:-

This page isn’t working

http://www.outandabout4x4club.org.au is currently unable to handle this request.
HTTP ERROR 500

I was advised by the previous user that all she did was try to update WordPress as advised, it then went blank and wouldn’t let her back in. I have tried everything to get it back up and running.

Please HELP! Many thanks.

Answer:

Internal server errors (error 500) are often caused by plugin or theme function conflicts, so if you have access to your Dashboard, 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 Seventeen theme to rule-out a theme-specific issue. If you don’t have access to your Dashboard, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, 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 SFTP or FTP, or a file manager in your hosting account’s control panel, and rename the .htaccess file. If you can’t find a .htaccess file, make sure that you have set your SFTP or FTP 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 specific time period. If you don’t have access to your server error log, ask your hosting provider to look for you.
