blank screen when updating products

Hi guys, I've got a site running 1.3.8.

When I go into the admin and then catalog->categories/products and select a product to edit, after I've done my editing and I click 'preview', the preview page comes up ok but when I then click 'update' to save the changes I get a blank screen.

The changes stick ok but it's annoying having to click in my bookmarks to go back to the admin home page rather than being back in the category list as it's supposed to.

I haven't stuck any mods on recently and I've only just noticed this problem, I suspect it's just a matter of a file thats become corrupt but I've no idea which one.

any takers :)

You might want to get from the Free Software Add Ons the Debug Tool and see if it helps to determine what might be the problem ...

Be sure to read the installation instructions carefully regarding installing the for the Catalog and the Admin ...

Hi Ajeh, thanks for the advice. Got that installed and found the error.

who's the daddy

What was the problem that you discovered? :smile:

The problem was to do with Simple Seo Url - SSU - addon.

There seemed to be some old code still in a file from whatever old version of this mod I had installed. Basically I had to go to admin>includes>update_product.php and comment out a couple of lines near the bottom - see here http://www.zen-cart.com/forum/showthread.php?p=637135&highlight=update_product.php#post637135

Thanks for the update on the cause of the problem ... it is always a help to others ... :smile:
