Blogs: Get newest first.The solution about line 358 in php doesn't work!

[heidig]

The problem is that when I set the params to show just one category ( {Blogs catid=cat1} ) the oldest posts is shown first. oldestfirst="false" doesn't work. I see that many others have had the same problem, but the solution that they used doesn't work in my blog.

After a serch trough the forum, I found several solutions where all was about line 358 in blogs.module.php. (Where you could change the end of the line from comments.createtime to entry.createtime, and then it should be ok.)

This was not on my line 358, but on the line 386. (!?)

I've changed the end of the line, but nothing happens. I'm a beginner in this, so I'm sorry if it's something that I've missed here.
Do I have to refreash the templates or something? I overwrited the php file, so I know I've done that right.
What could be the reason that this doesn't work? Is there something else I can try?

I'm using version 0.3.3.1

I'll be thankful if someone will answer me!
