I’m integrating the Connections plugin with a site containing a custom taxonomy named, curiously enough “connections”. It’s present as a mechanism for connecting posts to connections from the plugin database

For the most part, the Connections plug in plays well with that custom taxonomy, save for one curious (and repeatable) fringe case. If you attempt to view a custom taxonomy category page using the usual URL that looks something like this:

mumble.com/?connections=moof

the site replies with a fatal error

Fatal error: Call to a member function get() on a non-object in /home/content/59/8503459/html/gwizproductions/management/wp-content/plugins/connections/includes/class.scripts.php on line 226

specifically, it dies upon reaching this line of code

if ( ! $connections->settings->get( 'connections', 'connections_compatibility', 'jquery' ) ) return;

Apparently, $connections at this point in execution is not an object.

Similarly, if you go to the admin panel of the site then Posts -> Connections and then visit the posts associated with a particular custom taxonomy term, which is an URL that looks something like this

mumble.com/management/wp-admin/edit.php?connections=moof

the site replies in a more dramatic fashion

Warning: get_object_vars() expects parameter 1 to be object, null given in /home/content/59/8503459/html/gwizproductions/management/wp-content/plugins/connections/includes/class.scripts.php on line 143

I shut off all other plugins, I installed a fresh version of the core connections plugin, and the results are all the same.

Ergo, I’d conclude that the plugin is not playing nicely with the core WordPress category mechanisms when theres a custom category of the name ‘connections’. I noticed that connections.php declares a global variable named $connections – a common and unadorned name – and so my theory is that this global variable is clashing with something that WordPress is doing for the connections custom taxonomy.

BTW, if I rename my custom category to something benign like “eventconnections” then all is well with the world! (But this is a pain, for I have to unwind some existing code).

Anyway, you might note this a something to watch out for.

Thanks for the report … I’m going to have to dig deeper into this one. On the surface of it; it shouldn’t be possible to conflict with a taxonomy, especially with those URL/s.
