Cannot install plugin via admin interface

Hi!

I have a problem I not have been able to find on the forum… may be that my search skills suck 🙂

When I’m searching for new plug ins in wp-admin, I find a plug in and chose install, I fill in FTP credentials and file is uploading… but plug in is uploaded to wrong directory.

I have 2 wordpress sites on my domain. One is located directly in the root, and one in the underlaid folder “/blogg”. I have the same problem in both and plug ins are uploaded in to the same folder what is another sub folder: “/home/plugins”. This folder is home to my Joomla site.

If I upload plug ins manually it works

Can anyone help me please 🙂
