Hi there,
sorry for keep you waiting,
for
“On old Posts we are using often long Titels – what i have to do – to display it right in Breadcrumbs-Bar?”
please open you breadcrumbs.php file (you can find it here \shard\wp-content\themes\shard\inc\breadcrumbs.php)
on line 78 you have this:
echo $before . get_the_title() . $after;
Replace that code with
echo $before . substr(get_the_title(), 0, 10) . $after;
That number 10 is number of signs that will be displayed so put there some other number that you like :)
Cheers
