Our theme only supports paypal payment. If you want to use another payment, please install WooCommerce and use WooCommerce payment gateway.
I can see you installed WPML plugin and use it in your website.
And I can see search filter is working well. Please check https://www.batrantours.com/es/tour/?tour_types=93&page=0
Count for tour type in backend is not correct, because it is multi language.
Please add default tour types and translate it to another language. For now there are 2 tour types in english and 4 tour types in spanish. And default language is english.
And adding tours is the same. You should add a tour in default language and translate it to another language.
But you did not do like I said.
