[SOLVED][USE FC v3.1.0+ with J3.6.0+] client "suddenly" lost edit-permission for "some" items

hi there,

(glad to see you online again )

my client "suddenly" lost edit-permission for for "some" items, despite the seeminlgy unchanged and correct ACL-settings.
Also, it does not look like one category is affected, and another one is not;
It's more like a wild subset of items is affected:

Client-user logs into BE, goes to items-list, sees most items as not editable.
If client-user goes to items-list, ticks checkbox for an item, then clicks button 'edit' or 'change state', he gets 'you have no permission[...]'

Superuser sees seemlingy correct ACL to edit items, edit categories, edit state etc. for /all items/ for client-user.

The error may or may not exist since the recent Joomla Update 3.5.1 to 3.6.0
Is this something known to you? What can i do to resolve this?

Thanks for your time!

Hello

with J3.6.0
- you need to update to v3.1.0-rc2

also FLEXIcontent should now be more compatible with paid extension:
ACL manager
(but i have not tested it recently)

perfect, that works. thanks!
