Hi,

Suddenly all the attributes in all my models have become protected and  
I cannot save anything. Of course a solution is to add attr\_accessor  
for all the atttributes in all the models. But this was not the case  
before. All attributes were public.

Any idea how suddenly all attributes becomes protected?  
Any idea how I can make all attributes public again?

Please advise

Someone, somewhere is calling attr\_protected/attr\_accessible on your  
model ( a plugin could in theory do this for example)

Revert to previous versions using your version control system  
(hopefully you are using one, git is my favourite) to find out when  
the problem was introduced. If you are not using a VCS then now you  
know why you should 🙂

Thanks a lot for the help.
