Hi,

 Odoo was working great until today. When I try to create a company or duplicate one, I get the following error:

The operation cannot be completed, probably due to the following:- deletion: you may be trying to delete a record while other records still reference it- creation/update: a mandatory field is not correctly set
[object with reference: y1= - y1=]

I don't know what this object with reference means. 

Kindly help me with this issue. 

.S: I have seen on many threads, that the answers are given in Python codes. I don't even know where to apply them. So if you're giving me any code, kindly tell me what to do with it. 

Thanks a lot for reading.
