"Checkin or Checkout overlaps another booking"

Hi,

You ticked the small hotel mode. This means you want all rooms on the same name/type.
In this case the “list of rooms” should read room_name&rooms=9. (There are 9 rooms available of the type room_name) It is also possible to add more properties like room_name&rooms=9&persons=2&add_persons=1
So 9 rooms each having a standard occupation of 2 persons and 1 additional person as an option.

If you like to see the 9 rooms as separate room the setting (with the additional properties) should read room_name1&persons=2&add_persons=1,room_name2&persons=2&add_persons=1,room_name3&persons=2&add_persons=1,room_name4 ……

Regards,

Jan

I was getting this error as well without the small hotel mode on. Turns out that the room parameters NOT optional as stated in the description of the field.

At least in Dutch it says the extra parameters are optional but so far I was unable to keep the system working without adding the “display_name”, “rooms”, and “persons” parameters.

Jan, can you please verify that these are mandatory and that maybe the description needs to be changed in the settings section of the plugin?

HI Dick,

On my test system and operational system the additional parameters are optional.
I checked the code again but did not find errors. Maybe it is a php version related issue. Do you know the php version you using?
