User unable to upload Attachment (Frappe cloud)

Hi, everyone

Our site is hosted via Frappe Cloud. Yesterday, the site’s disk space became full with 25 out of 25 GB used, so I deleted some files. However, users are still unable to attach images or PDFs to the doctypes. I also upgraded the site to 50 GB of disk space just now, but the same error persists:

"Not permitted. No permission for Cash Book. User yada********@gmail.com does not have doctype access via role permission for document Cash Book."**

Two days ago, everything was working fine, and users had the necessary access.

Kindly assist if possible.

Thank you.

Anyone ?
