I accidentally added a CSS line to the Header Page CSS area (instead of the Global CSS) and received warnings on the top of my page. I immediately removed the added lines to the Header CSS, yet the warnings are still there. They look like this right now on my site www.MisterLevius.com :
Warning: array_merge(): Argument #2 is not an array in /home/misterl0/public_html/wp-includes/load.php on line 63
Warning: Cannot modify header information - headers already sent by (output started at…). php on line 348
Warning: Cannot modify header information - headers already sent by (output…) on line 360
Will it take care of itself (if so, how long?) or will I need to do extra? Hoping I won’t need to do anything in the cPanel. Thanks
