I tried to change the wordpress theme to f8lite. When I applied those changes, the website, and all its admin capabilities went down and the only thing that shows up in the screen is:
Fatal error: Call to undefined function add_editor_style() in /home/website/public_html/wp-content/themes/f8-lite/functions.php on line 15
I've seen some similar errors doing an online search, but haven't been able to fix it. Essentially, I would like to revert to the old theme I had.
I'm a noob at wordpress, but by looking at the code, I know somewhere there's an environment variable set to call the f8lite php scripts. Could someone please help me out in looking this up?
