When I create a new subcategory via the admin panel, the parent category doesn't load well any more : the loading stops at about 2/3 of the loading bar.
When I use the API for creating a new subcategory, I get the same problem. The insertion with my PHP program works, and the sub-categories are visible in the admin panel, but the parent category doesn't load completely anymore.
Do you have any idea concerning this problem ?
Thank you.
