sending email to my users in my forum

   
I am not sure if there is a help page here or not on the issue I am having, I searched and searched and couldn't find anything.
So if in fact this question has been asked before sorry for asking again..   

Anyway my problems is this, I noticed that when a new member came in, I went to send them a message by hitting send email, once I get there the box where I type my message the box is black, can't see if I am typing or what typed. I was able to send them a PM and Submit  a message on the there board messages, but can't seem to figure out why I would have a black box.
Here is the link to that page so that your able to see what exactly what I mean.

Hi,

Can you please provide both: Screenshot of this issue and forum version which you're using?

Thank you.

Tip: Instead of sending a message to each new member, try this: Go to your Administration Panel, and follow this steps:

ACP >> General >> Messages & Emails >> Private Messages >> Welcome private message * :

This will be send to new members who barely join your forum, mate. However, make sure that this option: Allow welcome private message : is enable.

Regards,
Sir Chivas.
