Ticket Template - Unable to process your request

Ticket Template - Unable to process your request

Hello.

Since yesterday i'm facing a problem in Zoho. 

Edited ticket templates for the past week and since yesterday having problems when editing. Message "Unable to process your request" when trying to edit any field.

Verified with admin coleagues and they can do it. My role remains the same as them.
Did logout - login, cleaned cookies and nothing worked.

Today when trying different roles in my user account it worked for a few minutes but then it continued.

So resuming : 

Same role/profile as before
Worked and since yesterday not
Tried with other agents with same role/profile and worked
Reset and clean cookies

Hoping for a solution

Thanks
