I can't even login to wp-admin, the page wont load. I tired to disable all plugins, doesn't work. I tried to go line 118 and have } change to <?php. Not sure what to do, I even tried to find the master copy of class-wp-widget-categories.php and replace the existing one... still not working...doesn't matter which domain i go to ...still showing the following:

Parse error: syntax error, unexpected end of file, expecting function (T_FUNCTION) in /home4/dom1014/public_html/MYDOMAIN.com/wp-includes/widgets/class-wp-widget-categories.php on line 118

What cause the problem!?!?!?!?!????

Has anything recently changed? Either way try the following.

- Create a fresh file backup of all your files on your installation. Save those somewhere safe and off of your web server.

- Starting with Step 1 at this article carefully replace your existing WordPress files.

If somehow your installation became corrupted then replacing the WordPress files with fresh copies may help get past that error message and let you log into your site.
