.htaccess: redirect with different subfolders

Question

Being not 100% familiar with .htaccess files, I spent already days in fixing one tiny issue, but with a huge impact. I want to create a line in my .htaccess file, which should be something like:

RewriteRule ^folder1/folder2/folder3/([^.]+)/?$ /folderA/folderB/page.php?variable=$1

I found out that the below piece of .htaccess code seems to work:

RewriteRule ^folder1/([^.]+)/?$ /folderA/folderB/page.php?variable=$1

But by adding /folder2/folder3, the RewriteRule is not working properly anymore. These extra folders are the only difference, but I must be doing something wrong.

Is there anyone who can help me out on this? I'm really lost...

Many, many, many thanks in advance for your help!

Answer 1

Invisible in my ftp, but visible within my Plesk server, I noticed there was a .htaccess listed in /folder2/. After removing that file, the line in the above described .htaccess works fine.
