Hello @webhostinghotel We have never encountered such an issue on our side. This can also be a server specific issue. So will have to check the issue and for that, we will need your FTP details and URL on which you are trying to install QloApps. Please raise a ticket and share the details here: https://webkul.uvdesk.com/en/customer/create-ticket/

Hello @Sheik I have already mentioned this error and its solution in one of the topic. Please follow this link to get the solution: https://forums.qloapps.com/topic/8/error-during-installation-all-parts-of-a-primary-key-must-be-not-null-if-you-need-null-in-a-key-use-unique-instead-error-sql-has-happened

@strangisgroup Let us assume there are 5 rooms of General Category in a hotel. Mario Brown books a room from 07-06-2018 to 09-06-2018 then for Mario Brown (the customer) check-in date will be 07-06-2018 and the check-out date will be 09-06-2018. And the check-out date of one customer can be the check-in date of another customer. Hence, on 09-06-2018 another customer can check-in in this room. So if Henry (another customer) books a room for 08-06-2018 to 10-06-2018 then the number of rooms available for him will be 4 rooms, and if he makes a booking for 09-06-2018 to 10-06-2018 then the number of rooms available for him will be 5 rooms. If all the 5 rooms are booked in that date range then it will not show that room type.
