Updated Xampp, exported database and moved folders in hdocs(modx folder).
moved folders back and imported database.
Everything else seems to work, but I am missing transport providers.
They are also missing from the database?
Have this error: [2023-05-09 21:08:19] (ERROR @ C:\xampp\htdocs\modx3\manager\controllers\default\workspaces\index.class.php : 158) Could not find the main provider for some reason with a name of "modx.com". Did you delete it?
Is there content for the database table modx_transport_providers in your database dump?
Just add the row for modx.com manually to the database table modx_transport_providers.
I am going to install Modx3.0.3 as a clean install, I guess nobody knows what went wrong?
