I'm attempting to set up the membership plugin at my site (www.fullcoursetravel.com)...I'm on WP 3.1.3
I followed the quickstart guide and enabled the plugin...after enable, I get the following error message for my 'Visitors' that are not logged into my website.
Warning: Cannot modify header information - headers already sent by (output started at /home/.../wp-content/plugins/all-in-one-seo-pack/aioseop.class.php:221) in /home/.../wp-includes/pluggable.php on line 897
Assuming this was a glitch with 'All In One SEO', I disabled that plugin and then I get the following error:
Warning: Cannot modify header information - headers already sent by (output started at /home/.../wp-content/themes/FullCourseTravel/header.php:4) in /home/.../wp-includes/pluggable.php on line 897
As long as I'm logged into the admin of wordpress I see the website fine, but when someone's not logged in, no posts or images show up besides the basic background images.
I've repaired tables inside of the plugin and they all look ok...not really sure what else to do.
If I disable the plugin, everything works fine...so it has to be an issue with how this plugin is communicating with everything else.
