Brief
We have updated the script 'friendly_url.php'.
Description
When there was selected the option "(redirect user to friendly url in case if he accessed page by common url)" in Settings > Global Settings then the friendly URLs stopped to work.
Solution
Download the updated version of the file:

Further, extract the file into the root folder of your shop replacing an existing file. Please do not forget to make a backup copy of the current file in case something goes wrong.
