hi
ive purchase this version Tour & Travel WordPress Theme and ive install the demo video slider.

2) demo single tour not working

Not Found
The requested URL was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

2) how do i remove Blog, shop and pages (dont need them)

3) i do i disable woocommerce plugin and keep the travel booking plugin active, can i keep the booking service ?

4) tour > singe layout 2, not available

5) im not gone offer payments in the website, how do i proceed ?

6) the Demo leave a lot to desire, it suppose to be something that is easy to replace keeping the structural availibility, but it requires lot of customisation.

7) theres a easy way to uninstall a demo and try a different demo ?
