I'm not sure if this is the correct place to ask this, or if I should send it to woothemes forums. I'm using Headlines on several sites in a multisite network (woothemes); I installed sitewide tags and now when the admins/editors/authors on the individual sites try to update a post, they get errors much like this:
Warning: Invalid argument supplied for foreach() in /home/famvin/public_html/famvin-org/wp-content/themes/headlines/functions/admin-custom.php on line 359
Warning: Cannot modify header information - headers already sent by (output started at /home/famvin/public_html/famvin-org/wp-content/themes/headlines/functions/admin-custom.php:359) in/home/famvin/public_html/famvin-org/wp-includes/pluggable.php on line 934
the updates are completed -- but the message is problematic and interrupts workflow and upsets them.
There is some sort of conflict, I think between some code in the theme (or the Woo Framework) and the plugin, I think. Ideas on how to get at the cause of the problem?
I will check at WooThemes to see if there are answers there (I've checked in the past, but maybe something has popped up recently);
