Trying to create a new chatroom in administrative backend results in error saying field can not be left blank when it actually wasn't.

do you have the latest version installed?
can you upload a screenshot of it here?

I have 9.6 installed on the Joomla 3.3.0 version.
Ok, this is strange. I went back to reproduce the error and this time I happened to look at the last entry field, Order:, and decided to change the number manually and the new chat room created flawlessly. I didn't realize you had to order them manually, I thought they would be assigned numbers as they were being created. Anyway, looks like it's working fine now.

Thanks
