Happened on MODX by chance, and I’ve been very impressed with it. A bit of a slog to convert my own stuff, but, once done, so easy to make mods and add new stuff. Template Variables have been a godsend.
There was a problem with Softaculous backup, though: it insists on backing up everything in the root folder, even though that contains subdirectories for other packages that are not referenced by MODX. So, broken-as-designed to my mind. However, it’s easy enough to back up to PC:
Download a dbase backup from cPanel
Logout of MODX and FTP to PC assets/, connectors/, core/, and manager/, plus .htaccess, config.core.php, and index.php for completion’s sake.
