@Barry,
I tested all my plugins and all plugins and my theme work fine with the venues section state dropdown except for when I activate WooCommerce Subscriptions. I already added the fix recommended earlier which fixed the
state dropdown issue in the actual create events section, but the Venue area still has a frozen dropdown menu. For now, in the Venue section I figured out that if you put a zipcode in the state field it shortens the frozen dropdown list allowing me to click into the hidden fields behind it and I am able to blindly type in them filling out the information and able to create new venues. However, please let me know when you have a fix for the Venues section with the WooCommerce Subscriptions conflict.
