Hey [deleted],
Just wanted to let you know. By default in Flarum you can only have a title limit of 80. I saw in your post history you have (likely) edited yours to be custom.
For the average user of Flarum, me included, I have posts not being made because of the limitation.
A quick, very dirty, work around is as follows
$subject = $item->get_title();
to
$subject = substr($item->get_title(), 0, 79);
This functions as a horrible fix, but will mean all posts made by any user setting this up works.
