Restrict content affecting posts, forums and topics

[Chrislancs]

I have inherited a WordPress site and I am learning on the go, although I have a million miles to go! I am no expert.

I have the restrict content plugin and everything was working ok. Then, perhaps triggered by my WordPress upgrade it seems to have become the source of serious problems. When I go to create a new topic, forum, post I get a ‘messed up screen’ which means I cannot do anything and I receive the following message at the top of the screen:

Notice: Undefined index: rcMetaNonce in /home/studentpanel/public_html/wp-content/plugins/restrict-content/includes/metabox.php on line 85

When I deactivate this plugin everything starts working again. However, the plug in is useful so I would like to understand and resolve this problem.
Any help warmly received.

Is WP_DEBUG enabled on this site?

I have WP_DB Manager on there as it looked safer for my site.

I am happy I found this thread. I was really scratching my head about this error and it would have probably taken me ages to find out that Restrict Content is the reason for it.

I have the same or similar problem, it happens when a script (from a plugin I am working on) inserts a post in a custom post type.

WP_DEBUG is enabled, shows the same error message as Chrislancs gets.

Notice: Undefined index: rcMetaNonce in […]/wp-content/plugins/restrict-content/includes/metabox.php on line 85

The problems gets “worse” when trying to delete the post. After clicking on the “Trash” link, I get a white page saying:

Notice: Undefined index: rcMetaNonce in […]/wp-content/plugins/restrict-content/includes/metabox.php on line 85

Warning: Cannot modify header information – headers already sent by (output started at […]/wp-content/plugins/restrict-content/includes/metabox.php:85) in […]/wp-includes/pluggable.php on line 1228

As stated by Chrislancs, the problem goes away when deactivating the plugin.

I guess the code that handles the “rcMetaNonce” post_meta entry needs to be revised.

I’ll try and get an update out in the next week or so to resolve this issue.

No, sorry, I’ve been unable to address this issue yet.

Actually I’m going to push out an update now that takes care of it.
