Hello,
To enable RTL direction you will have to edit the file /data/config.php and add the following line:
define('DIRECTION_RTL', 1);
This will switch the direction to RTL for all users on the given installation. We have plans to include LTR/RTL switch during the setup of EPESI.
We don't have anyone in our team familiar with using RTL direction, so if you find any inconsistencies with the expected behavior in RTL version, please report them to use with desired resolution.
Kind regards,
Arek
