I use Moodle Cloud and recently copied over an older course from 3.x. Links within that course to YouTube never take me there--I just get a spin.
I searched for reasons why it might be slow and found that the Performance Report notes that I have an error that the "database schema is not aligned."
As I'm using Moodle Cloud, I lack the skills and ability to dig into the schema to align it.
Help! And thanks.
