Dunno whether this might help troubleshooting font and/or line_height: an image I had on some content displayed upside down (!sic) until I removed font & line_height, when it reverted.
Uninstalled Line_height AND Font which fixed things. Will try uninstalling CKEditor5 and reinstalling the whole kaboodle; #7 makes this sound like a solution; however if #8 proves to be my case too, then I'll live without Line_height and/or Font.
Almost 2 years later, I'm having this problem ("The provided host name is not valid for this server"), and it ma have something to do with SSL because I've set up a subdomain not covered by my certificate, and that's where the problem arises (D10). Can you remember what it was you "corrected" regarding SSL?
I've got this problem on 3 sites on different servers. Unfortunately rolling back to 10.2.7 is an ugly option because of "3456958-bookoutline-plugin-does" which prevents updating content. I say ugly option because uninstalling the Book module requires deleting all content in books. I'm stuck with 3 sites unable to move forward (or backward).
Whitespace in patch
I dunno if this will help, but I received an Excel spreadsheet which I saved as .CSV. A 'required' field in my content type reported "Your CSV has missing required fields:". The problem was a space after the heading name ('field_order_form ', a required field). If the space comes after a non-required field name, it just doesn't upload the data. The spaces aren't easy to see, and they didn't matter to the visibility in the original Excel sheet.
I'd like very much to see that, too.
I've got the same problem with Recurring Dates Field. Cron throws "Drupal\Core\Database\DatabaseExceptionWrapper: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'monashee_vendors.date_recur__node__field_delivery' (delivery is a date) doesn't exist:" during execution of field_cron(). So I guess some field(s) are not getting removed. Must I rebuild the table ??
nd_pdo_mysql wasn't selected. I deselected then reselected mysqli and mysqlind.
