Unable to move or copy products between categories - blank page

I have a customer using Zencart v1.3.7 db 1.3.7, the issue is that when trying to move or copy a product, Zen admin comes back with a blank screen after about 15 seconds. There is no error message.

On unique thing about this cart is that they have over 40,000 categories. We also get the same blank page when turning on the Go To: function in the product admin, we had long since turned this off because it slowed product admin due to the high category count. Could we be experiencing a timeout?

I know this used to work when the category count was around 30,000. Another note, we have written import scripts to import a large product / category database into the cart.

I have other customers on the same server running the same version that do not have the issue, of course they have far fewer categories.

Any ideas?

The post about logging errors fixed the issue. I was getting an "PHP Fatal error: Allowed memory size of ....." I just needed to update my php.ini on the server to increase the size limit. Thanks for the help.

Thanks for the update that all is working now and for posting the solution to this problem to help out others with similar errors in their php.ini settings ... :smile:
