==================
I recently upgraded from version 3 to the above mentioned version.
Now i am facing problems in adding multiple options in survey!
I get 500 error on ajax call and the flowwing msg 
The table "{{tokens_0}}" for active record class "TokenDynamic" cannot be found in the database.

 Is this a know issue with this version 5 or i am doing something wrong 


I have attached the screen shot of the error 
 
 

Unsure here,
Able to update to 5.6.65 ?
