try

dashboard>settings>permalink and just click save – this resets the permalinks and sometimes fixes

No 🙁

Fixed
Thank you!
I hadn’t space in database sorry 🙂

once activated go to
dashboard>settings>bbp style pack>Breadcrumbs

I tried but unfortunately when I save it doesn’t save the changes

for the furst two, add this to your theme custom css

.forum h1.page-title, .forum div.page-description p {
display : none ;
}

When I try this, I have this error:
changeset_post_save_failure
