Hello, I'm no longer able to create product combinations with PS 1.7.8.2 (same thing with 1.7.8) and it's no longer possible to search categories when creating a new product. I was able to solve this issue by reuploading a fresh admin folder but the issue shows up again as soon as I refresh the page. I tried with several browsers, computers, tried to clear cache, delete cache folder...without success...
Attached I added my debug log.
