Moving to another server and updating

Did you update the .htaccess file ? (permalinks) ?

Yes. I opened the WP Options and copy/pasted the new .htaccess to the WP directory.

I alsy asked the admin of the server if mod_rewrite was installed and running correctly and that’s ok.

Are the <IfModule mod_rewrite.c>-tags necessary?

Update:
The normal posts (without rewriting) are working without a problem.
Example: https://branders.name/index.php?cat=2

So this seems to be a RewriteRule problem.

Here is my .htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d

I’m no mod_rewrite pro, but why don’t you take that out and see if it works?

mod_rewrite is a pain for most.
personally I am happy with index.php as part of my url. I still use permalinks like you.

I’m trying to make the URI’s almost the same as on my other server. Everything worked OK there…

I think the transition from one server to another has something to do with it. Maybe an option that’s not interpreted correctly or so.

DianeV: Removing the IfModule tags didn’t help. Same problem…

OK, I found the problem… It was a mistake in httpd.conf, the Apache configuration. I read the solution in another topic and mailed the server administrator. A couple of hours later, the problem was fixed.

Thanks all for your help! ??
