I have a Magento 220.127.116.11 store and I've installed an extension(by uploading everything that was in the archive trough ftp). It is now visible in the top menu bar in the admin section(it doesn't appear in
System > Configuration) but when i click on it it leads me to the front of my store
404 error page.
I tried to reinstall the extension, then reset the roles(found that as a solution to a similar problem) then log out and in again but the problem is still there.
I was thinking about installing that extension trough Magento Connect but the same 404 error page appears when i click on
System > Magento Connect > Magento Monnect Manager.
