WordPress Site Having Fatal Error in Root View

Solution:1

The problem is in your theme somewhere. If you have another theme installed (but obviously inactive), use this guide to change your theme to something else while you troubleshoot the problem.

Solution:2

There must be something wrong with your theme. Connect to your site’s FTP server and move the folder wp-content/themes/resca to another folder (such as the root) or download and then delete it. You should then be able to log into the backend and set another theme.
