Iver - Modern Hotel Theme

We are developing a website for house rentals in Naxos Island Greece and we are using your theme on WordPress. We have run into a problem/error on the theme. We are using WordPress 5.9 version and woo commerce 6.2 although we read on the change log of the theme and we downgrade to 5.5 WordPress and 4.6 woo commerce but the problem kept going.

The problem is this Fatal error: Uncaught Error: Call to a member function set() wp-content/plugins/woocommerce/includes/class-wc-cart-session.php:197

The problem appears when you go to Woo Commerce > Orders > Order, where the order details of the have errors. Now we found a way around the problem but it will destroy other parts of the theme.

/var/www/vhosts/naxosaffinityvillas.com/httpdocs/wp-content/plugins/iver-hotel/post-types/hotel-room/helper-functions.php(1167): at this location their is a function call WC_Cart->empty_cart(false) we commented out this and the cart start working but we got other errors afterwards.

We need to fix that error so the full order and other problems will be fixed.
We can create an account/user for one of your developers to go in and test around.

We now try to downgrade the Woo Commerce and WordPress to the accepted versions, but the problem persists. We know that our support was expired, but we now need to decide weather we should rely on your support and renew it, or go buy another theme. Please helps us!

Hi, this is a general forum, please contact the author of the theme here:

Hey! Thank you for your answer. The author doesn’t provide contact options. Only by paying the support fee.

If you bought the theme on ThemeForest then you are entitled for six months of support, no need to purchase any additional fees within thit period.

Hello and thank you for your reply.
The theme was bought by another developer, and after many months of not managing to set the website, we came and took the project from there. So the 6-month support period is expired…

Then unfortunately, you will have to extend the support to get additional six months of support.
I mean you can always get in touch with the author via item comments, even without extending the support, but the author does not have to help you unless you do extend the support:

Thank you so much! That was very very helpful.
