Okay so I have a magento store with 1000+ products and never encountered this issue before.
I have added a new category under Hangers, basically I have 8 different sets of hangers 4 suit hangers and 4 shirt hangers... At first I added all 8 of them to a new category when doing that the category store page would just be blank. I did trial and error for an hour eventually i added one by one... They showed up, eventually all 4 suit hangers show up on the page. Now as soon as I add one of the shirt hangers to that category the whole page goes blank.
To me this is a new one, I am not sure why adding a specific product to a category would cause the whole category page to go blank. Any ideas would be appreciated. Thanks
