I disabled Nextgen but didn’t know how to try the cart without it since the only items I have are set up through the gallery.
I reinstalled WP. – Didn’t help.
I deactivated all plugins. – Couldn’t find culprit.
Deleted all plugins that were installed but not active just in case that could be it.
I changed themes to see if that was causing the problem.
Tried both Mozilla and IE just to see if that could be the problem.
I looked for any session_start() code in the index.php file. I didn’t see anything. I doubt this is the problem but I’m curious about who starts the session. I would expect it is the shopping cart plugin.
Any more ideas?
Thanks for the troubleshooting advice. WP is up to date. I’ll try the rest.
I did both of the things you suggested and the problem is still there.
