Hi bayijiy bayijiy,
I have someone looking into it, since those guys here any not replying, although i have extended/renewed support paid for :/
I've managed to get the calendar back, but now there's another issue - once a customer chooses the date and how many guests and they click on "book now" - the new window opens, as usual.
But, it states "you cart is currently empty".
Maybe it's important to say - once i'm logged into my website's wpadmin panel - there are no problems at all.
the calendar is there, the shopping cart is there, etc..
But, naturally - no client can do that.
So, therefore, i have a problem - nobody can complete the order and purchase our tours.
Hopefully, the guy i've hired to fix it would solve the problem soon.
If not, i'll reach out to you.
And also i'll submit the refund ticket to PayPal for the theme's authors to refund my support payment - since they are providing none.
