Crikey after update / Unable to find the wrapper "blueprints"

Hi ,

I just tried to update a Grav Site within V 1.7.

unfortunately i got an error during the update process an i am really not sure, what i exactly did wrong.

the site now shows an Error

“ErrorException (E_WARNING)

file_exists(): Unable to find the wrapper “blueprints” - did you forget to enable it when you configured PHP?”

The Error is sent by user/plugins/flex-objects/flex-objects.php

obviously i forgot something …

can anybody help me please with a hint where to look closer ?

Thanks a lot

odde

update: solved - but not sure why

after removing the suspicious yaml file from user/blueprints/flex-objects/

the site looks good again.

For some reason i tried to reinstall the yaml file again an got no Error.

i think i have to do some further reading about blueprints.

sorry for bothering you
