[Plugin: Restrict Categories] Doesn't seem to work with my install (implodes)

Does this happen when you install and activate or after saving your options?

ilen,

I have updated the plugin to no longer require implode. Please update to version 1.1 and let me know if that fixes your problem.

Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/…/wp-content/plugins/restrict-categories/restrict-categories.php on line 204

What do I have to change to get the plugin working?

Have you tried deactivating all plugins besides Restrict Categories? What version of WordPress and PHP are you running? Also, can you list your categories here?

Thanks for the quick response.
PHP version: PHP 5, MySQL 5
Wordpress: 3.0.1.

A post will have always a combination of two categories: region south, best practice. I want to organize the posts per region.

I tried to work with the plugin and when I choose the categories for a role the error message disappears and the plugin works.

So, you got the error before selecting any categories, after first activating?

I got the error messages (just before every category) after I activated the plugin and visited the restrict category pages. The error message disappears when I choose one or more categories.

I’m not able to reproduce this error on my setup of PHP 5.2.11 and either WordPress 3.0, 3.0.1, or 3.1 alpha.

Let me know if you have any more errors.
