Few Problems and questions

Hey, I have a few problems about new updated, and problems.

Firstly when I create new tournament no buttons seem to act. I can click them allright but there is no effect. What follows I cant edit any tournaments, make them premium or even launch.

Secondly in my “apperance” tab I cant see theme option section. To go to Arcane options, change colours etc. There is a wider gap between one and the other option (emails and install plugins) that I can click to go there. But its kind of annoying.

Thirdly I get this error in tournament module in my mainpoage (vew tournaments)

Warning: Invalid argument supplied for foreach() in /home/klient.dhosting.pl/insiemo/reconnect.gg-eiw7/public_html/wp-content/themes/arcane/addons/tournaments/extended_functions.php on line 2280

Whats with that?

About the pay to join feature. I understand that I can create that product in woo, select “join all premium” and the member becomes a premium member that can join all premium tournaments. For how long? Can I set till the end of the month or 30 days? Whats more can I set member to premium manually? I have a physical club that you can come and pay those prermium fee. How can I then change user that created account and paid me face to face to allow him to join premium tournaments?
