I'm getting the following error message when I try to view my blog and blog dashboard. I can only address problems via cpanel.
(Warning: array_merge() [function.array-merge]: Argument #1 is not an array in /home/spider/public_html/mywebsite/wp-includes/cron.php on line 320)
The following message also appears
(Warning: Cannot modify header information - headers already sent by (output started at /home/spider/public_html/mywebsite/wp-includes/cron.php:320) in /home/spider/public_html/mywebsite/wp-includes/pluggable.php on line 881)
I'm totally stuck and any help would be appreciated.
