Hi,

I just transferred a site with Joomla 3.3.3 and K2 2.6.8 from a LINUX server to a windows shared hosting with IIS and apparently everything is working fine, except for two details that I am not able to resolve.

One has to do with an error (Page not Found) when I click a link in a K2 TAG with accented characters (eg férias)

Another problem is that i can not perform site backups with the backup component Akebba Backup. It returns the message "Unreadable directory <my root directory>" and the backup file contains only the installation folder (both JAr as Zip) .

There is a setting in IIS for handling non-utf 8 links. You have to contact your hosting provider about this.

Another scenario would be to enable SEF URL character replacements in K2's params.
Joomla! 2.5 or newer has a setting for this as well.
