Hi,
this issue i had is similar to the mentioned in "frustrating issue" .
When i add a very simple rewriterule like this
^article/([0-9]+)$ viewtopic.php?t=$1
it append "article/" after domain name in all the links in the page so on image are loaded and others related problems.
It happen even if i use rewritebase /
Any ideas?

Yo ppl!
270 viewed time and no answer ? Looool
I thought it was really an easy issue.
Ok i explain more maybe it's not clera enough.

When applying the above rule all links in the page will have target like this.
www.mydomain.com/article/viewtopic.php?t=..... and so on , the image too have the src appended with "article/" so no img is loaded.
When removing article/
from the rule all become ok.
Any ideas.?

Should we guess how you have written the rest of the rewrite rule.

part of the code is of absolutely no use at all.

shall i guess which part of the rule is off?
The whole line as mentioned above.
RewriteRule ^article/([0-9].*)$ viewtopic.php?t=$1
