Hi Joe! thanks for reply, these are the versions i’m using:
Wordpress: 5.6
PHP: 8.0.3
My Calendar: 3.2.17
This is the line of code where error is being produced:
$note = sprintf( $note, "<code>$value</code>" );
I discovered that this error could be avoided deleting the value of “Date Format for multi-day events” field, when default value “F j-%d, Y” is deleted, text settings can be saved without display the error…
