Wordpress Plug In Issue & Website Maintenance

详细信息

I need someone who can fix an issue with a wordpress website that uses WP Booking System plug in.
The calender is only showing on this page https://montenegrovillaholiday.com/villa-maslina-durasevici-lustica-tivat-montenegro/
It was showing on these two pages but for some reason is no longer there.https://montenegrovillaholiday.com/villa-mandelina-durasevici-lustica-tivat-montenegro/https://montenegrovillaholiday.com/villa-josephina-durasevici-lustica-tivat-montenegro/
The plug in details that it is compatible up to WP version 6.4.4 and it is running on WP version 6.5.2 so this might be the issue.
I also want somone to check the website on a monthly or quarterly basis for updates/ issues / compatibility / security etc.
