Thank you for purchasing our plugin. I’ve investigated but TML plugin works perfectly on our end & the site is also loading don’t know why it’s not working on your site. It seems the login is also working on your site as registration is disabled from backend that’s why the page is not loading.
About regions you won’t need to install it as the regions load from ads which are published. If you see we get address from ads & the country/state or anything within that dropdown loads from those options.
It shouldn’t be happening. There’s no options or something that hides your editor option must be a plugin which is causing this.
You can change the language easily using WPML plugin. Or else you can translate the .pot file to your desired one. You can translate the .pot file using poedit software.
Hope this will help you in cases. Let us know if you need any more help.
