Hi,
i am not able to sort or save entries in my team folder anymore:
this error occurs, when i try to save the parent page, as well, when i try to save a child entry.
i am not very experienced with grav, so maybe someone can at least hint me in the right direction.
thanks in advance 
I found the 2 culprits.
first, i had a problem in my blueprint.
in my default.yaml i had a field “route” with
options:
‘/’: PLUGIN_ADMIN.DEFAULT_OPTION_ROOT
that did not work, i removed it. the error went away.
but even after that i could save, but i was not able to order 1 specific item of my list.
my sortable items were like
and i was not able to move the folder 11._001_Philipp to a higher position.
that went away when i put the caps in the folder name all in lower case to 11._001_philipp
then ordering worked again.
