I went on to editor and deleted an entire PHP after i copied it onto the clipboard. After finding out whatever I was trying to do didn't work, i pasted it back into the PHP and saved it. After saving however, I can't proceed to any page other than the one I'm currently on because every time i click on a different page, it brings me to a blank screen with the words "Fatal error: Class 'TC_slider' not found in /home/anahei7/public_html/wp-content/themes/customizr/functions.php on line 54" on it. The only thing I can do is press back and stay on that one page.
Please help.
