Fatal error: Cannot call method self::form()

$callback = ‘self::’ . $prop;
change to ->
$callback = ‘WPCF7_ContactFormTemplate::’ . $prop;

Hi guys,

I’m having the same problem, but don’t know where:

$callback = ‘self::’ . $prop;

Is to be found. Can one of you please walk me through it?
Thank you so much!
