Question Forum thread text not showing

One of the uses sent this. I've looked around but can't seem to find anything.
Please point me in the right direction.

We recently migrated to a new server and a new installation of Joomla.
I had backed up the individual tables associated with Kunema. Then I did a new Kunena install on the new site and imported the Kunena tables.

Here's the issue now:

I'm getting some strange problems when looking at the forum. some of the posts are just white space. The words are there if I highlight them I can read it. It's almost as though the font colour was set to white. This only happens on some posts and not others.

for example
www.zeitgeist-canada.com/index.php?optio...c=view&catid=5&id=95

I can see the movie and the text in the reply afterwords, but I can not see the text in the original post unless I highlight it.

Please advise.

1. In your JOOMLA template css file (template_css.css) on line 6 you have

body, td, th {
color:#FFFFFF;
font-family:Arial,Helvetica,sans-serif;
font-size:11px;
line-height:160%;
}

change color:#FFFFFF; in something else or delete this line

2. If you have problems in other part of site with first solution you can add red colored line in kunena.forum.css on line 774

#Kunena div.msgtext {
border-top:1px solid #DDDDDD;
color:#444444;
margin-top:5px;
overflow:hidden;
padding:10px 0 0;
width:100%;
word-wrap:break-word;
}

Many thanks.
The first solution worked @quila, and text is again visible. Thanks for both.
