Tried to upgrade to latest version of WordPress but couldn't because my php version is not updated. Downloaded new version of php but still could not upgrade WordPress. Then I updated my plugins and now I cannot log in to the site and have a screen full of error messages.
Here's what I get when I try to log in: http://cambriahistory.org/wp-login.php
Here's what the site looks like: http://cambriahistory.org/
How do I log into my site now?
