can't access product category : maximum recursion depth exceeded in __instancecheck__

[Olivier Van Helden]

I was creating categories and sub-categories of product by duplication of the previous record and I can't access the product category menu anymore.

Error message in attach.

In the 5.0 branch.

Hello Olivier Van Helden,

We are unable to re-produce the error message. As it works pretty fine at our end.

Would you please provide me in detail the steps you follow and the version which you are using?

Thank you.

Hi,
I think that you have a cyclic definition of product categories. In the past
I had the same error (I do not remember wich version of 5.0). You can corect
this issue with direct access in database table (product_category).

During the duplicate of a category, I probably miskeyed something and the category has itself as parent.catgory.

I wonder how it occured.
Creation of any such category would fail and a message will be popped up not letting you create recursive categories.
Would you please retry?
Thanks.
