Hello, After a long time not using Mailwizz I decided to restart some campaigns and the first one I attempted got stuck at the pending-sending stage. Seeing that I was behind a lot of the updates, I decided to update the app hoping this was going to be a walk in the park. Now I have an error message when I go to: http://www.yourdomain.com/backend/index.php/update I followed the instructions from this page for the update: https://kb.mailwizz.com/articles/upgrade-steps/ I used CyberDuck on Mac to upload the "update" folder of the latest version on the app from CodeCanyon, and I made sure this was set to "overwrite." I even contacted the server guys for my VPS and they said it's not an issue with the server. I have just renewed my support package and hope to find a solution with your help. Thank you.
