List Contacts, and send file

hi guys, sorry, please help me using Openfire 4.9.2, build dd3cca6, I have 2 problems, the first I failed to send images or files, the second the existing contacts are not included in the list even though they are online, what should I do for both?
thank you

Hello! I’m afraid that you’re not providing enough details for anyone to be able to help you with these problems.


Why don’t others appear listed there when they are online?


and then i can’t send the file and no error appears

On Spark, are you using ‘Actions > Start a chat’ or ‘Contacts > Add contact’?(you should use that latter).
And for the file transfer, you need to talk to your Openfire admin about this. People these days prefer to use the httpfileupload plugin for file transfers. But it depends on work environment policy.

Thank You
The first one is already on the list but the status is pending


the second one i still can’t send the file
