"Please Fill In These Fields First"

Everytime I go to compose a message, I get this error. Any ideas? 

	PLEASE FILL IN THESE FIELDS FIRST

Hello

This message can appear if message's Subject or Body  was empty when you tryed to send a message. By default Dolphin has JavaScript checking which prevents the message to be sent without content but for some reason it doesn't work too. If you provide your domain name and test profile access info I would be able to check it and give you more detailed answer.

This message is appearing without even showing the fields to make a message. 

I have temporarily allowed users to access the Join page... 

Domain: http://my-cabinet.com/

Any Suggestions?

Hello

I checked your site and default Dolphin's MailBox and as I see this mesage cannot be displaed on Compose page loading. Looks like you did some custom modification for MailBox which tries to send a message automatically or something like this. You need to undo it or fix to work correctly. The page is created with templates/base/scripts/BxBaseMailBox.php file -> getBlockCode_ComposeMessage function.

Hello, 

I noticed that I can't compose new messages. When I go to Compose Message than I get this message: 'PLEASE FILL IN THESE FIELDS FIRST'

Why is that? Has anyone solved this problem?
