Your main page isn’t working, but admin is right now. Have you performed any recent changes to your website?
No i have not accessed the website since i made my last post in december of last year.
I have seen this before. If you’re on an older version of WordPress, go to this file: /wp-admin/includes/screen.php
When you’re in that file, search for “self::” and delete the “self::” every time you see it. Save the file and try your dashboard again. It should be fixed.
Other things that can cause that, if you’re using an older version of wordpress are:
If you are using a newer version of php than wordpress is setup for, (for instance php5.4 when the wordpress version is below 3.8). In that case try using php 5.2 -> upgrade anything on the wordpress that says it has an upgrade (themes/plugins) then upgrade wordpress to the current version.
A plugin or theme that displays info in the admin that doesnt work on the current version of wordpress, or version of php. Usually your error_log will have something in it that lets you know what plugin is doing it.
