Filestation - unable to perform action you do not have enough permission or this folder is read only

Model: TS-228A
Current firmware version: QTS 5.2.4.3092

Using the admin account
access to shares within another share have stopped working, this is only a problem for filestation 5
Accounts given R/W access to “folder” share can access the folder over SMB but when I login as admin over HTTP im getting the following error.
“unable to perform action you do not enough permission or this folder is read only”

this seems like a similar error that has occured in the past and was previously fixed with a firmware update see here → Filestation - unable to perform action you do not enough permission or this folder is read only - QNAP NAS Community Forum
