Greetings, Subrion 2.3.6 release is mainly dedicated to the installer and upgrade functionality of our software. We made a lot of improvements that will allow us make easier upgrades later. Here is the changelog: Unfortunately this patch can not be applied in the same way like you applied the previous versions. Upgrade instructions 1. make backup of your files + database 2. Download from our website patch 2.3.5 to 2.3.6 ____ READ CAREFULLY _____ 3. unpack it locally, upload the following file: updates\upgrade_v236.sql to your core updates folder 4. go to admin panel -> manage database -> import, run this upgrade file ___ 5. Upload all the files from patch over your files. That's all! The main point is to run SQL update file BEFORE files reupload! Please let us know if you have more questions.
