Hi bachma. Welcome to the forums :)

I'm gonna go out on a limb here and say it'll take 3 steps to fix the problem:

1. Post a link to your blog
2. Expect a couple of test comments
3. See what someone has to say here after they comment and can actually see the specifics of your installation and the 'bad request' error

Aw crap it'll be more like a million steps cuz then it'll be "do the fix or maybe resolve some questions" followed by maybe repeat followed by eventually you saying "cool that worked". But anyway it'll probably start with those three steps ;)

Thanks!

Here is a link to one of my blogs for testing:

Well now ain't that strange as all get up! Obviously it posts and I can't see anything obviously funny about anything, but yet it throws up a very generic error page. Not a b2evo page. I shoulda kept it handy but oh well.

So a couple of thoughts in random order: try a different skin just because it will prove one way or the other if it is in your skins/miami_blue folder or not. evopress or custom should be pretty danged reliable ... not that miami_blue shouldn't be.

Also we can jump straight to my favorite sledge hammer for weird stuff: total replacement of files. Imagine if somewhere you have one bonked up file. Might have gotten there when you first downloaded, or unzipped, or uploaded, or just happened on your server. So let's kill it without trying to figure out exactly what the deal is. Get a brand new copy of your version (download link above), and unzip it on your computer. Connect to your server web space (FTP or host-provided tool) and completely delete your existing /htsrv/ and /inc/ folders. Wipe 'em out. Now upload the ones you just downloaded and unzipped.

Finally, let's hope someone smart enough to not just guess comes along :)

Thanks for the help, but still no luck. Tried replacing the skin, as well as replacing the htsrv and inc folders, still throwing error page although the comments are being posted.

See if this helps http://forums.b2evolution.net/viewtopic.php?t=13798

The best thing you can do is move your blog to Linux/Unix platform if your hosting provides this option.

BTW do you receive emails from your blog?

Yes, I receive emails from my blog. Also, here are the lines from the template.funcs.php file, which I have not changed since it looks similar to what was suggested:

// <fp

/* fp>why do we need this?
dh>because Location: redirects are supposed to be absolute.
if( substr($redirect_to, 0, 1) == '/' )
{ // relative URL, prepend current host:
global $ReqHost;

$redirect_to = $ReqHost.$redirect_to;
}
*/

It looks similar, but it's commented by default. Uncomment the code.

Beautiful! Works like a charm after I uncommented the code. Thanks for all the help. You guys are great.

no problem
