I have noticed that the stylesheet in DNN Forums 4.4.3 has an incorrect entry for the following:

.Forum_RowHighLight1 {}
.Forum_RowHighLight1_Alt {}
.Forum_RowHighLight2 {}
.Forum_RowHighLight2_Alt {}
.Forum_RowHighLight3 {}
.Forum_RowHighLight3_Alt {}

Both Firefox and Interent explorer do not render the borders on the forum rows because the case is incorrect. I see that even the DotNetNuke forum has this incorrect syntax.

If you chane the RowHighLight entries to a lower case "l" you will get your borders on the rows.

You entries should be:

 .Forum_RowHighlight1 {}
.Forum_RowHighlight1_Alt {}
.Forum_RowHighlight2 {}
.Forum_RowHighlight2_Alt {}
.Forum_RowHighlight3 {}
.Forum_RowHighlight3_Alt {}

I have an example of my skin on Stymies.net

Hope that helps!

Sorry if this is a duplciate post but I did not find anything in a search of the forums.

Thanks Thomas, how do you troubleshoot this kind of issues?

I have looked at css but couldn't notice this until now.

Well explained.

For those lazy folks, you can download modified css file for default Forum Theme from my website.
