Hi there.
My tickets are not showing in my events.
It seems that my theme does not suport woocomerce or something like that, but that was not in your terms and conditions.
If your theme doesn’t explicitly “declare” support for WooCommerce then yes you will see a warning notice to that effect, generated by WooCommerce. Often it can simply be ignored, however.
You seem to be using quite an old version of WordPress – can you also confirm which versions of our plugins – for both The Events Calendar and WooTickets – you are using (just visit the plugin admin screen to determine this)?
