I keep getting random warning messages while using the WordPress backend and while on the site, but they do not always occur.
Warning: preg_match() expects parameter 2 to be string, array given in /home/mydomain/wp-includes/class-simplepie.php on line 1727
Warning: Cannot modify header information - headers already sent by (output started at /home/mydomain/wp-includes/class-simplepie.php:1727) in /home/mydomain/wp-includes/pluggable.php on line 934
ummmmmm, help! LOL
P.S. I have already posted this in the DIY support forums and they do not seem to think this is a problem related to the Thesis theme.
