Error trying to enter a tournament

Hello,

When I try to enter a tournament from any kind of user I get a javascript console error: Cannot read property 'toString' of undefined. I dug a bit deeper, and it seems like this jQuery function is returning “undefined”: jQuery(this).data("gid")
at document and line: tournament-scripts.js:516. So that when it gets to the function arcane_filter_teams (line 1), it receives undefined as argument.

It seems like “gid” stands for game id, and the html element was never set a game id as data. I didn’t want to dig deeper since I think the devs will probably know what’s going on.

I’ve also been trying to figure out if the problem was with my wordpress. I’ve tried deactivating all the plugins and nothing worked.
