Blank page after adding new category and a product in it.

Good afternoon,

I'm having a problem with our Zen Cart website.
Everything worked perfectly until... Actually I do not know until what.

Now the situation is the following:

If you go to our website: https://www.astronomy.lt you will start at our start page with our native Lithuanian language and our native currency. If you try to change Currency to EUR, then you see a blank page. But if you push "back" on explorer window, the content goes back and shows price as requested in EUR (and vice versa).

Today we found that we cannot add new category and a product in it. We can add a category in admin area, then we can add the product in that category, but after trying to get in that page from normal explorer - only blank page without any words is displayed.

Please help, because we do not know what to to... Other Categories and products that are in them or new products that are inserted to old categories work fine.

We are using:
Zen Cart 1.3.8a
Patch: 1::
Database Patch Level: 1.3.8

The Only changes that we made were adding multilanguage EZ pages addon and aplying the latest patch from Zen Cart.

Thank you in advance.:cry::blush:

Lukas Jonaitis.

Hello,

Does anybody have any ideas?

I have checked the website and found that the same problem is with manufacturers. For example, if you click on the appropriate manufacturer, then you go to that manufacturers products... But it works on some manufacturers, and on others - fully blank page. ;(

A quick stroll through the FAQs area and doing a search on "blank page" brings up this article ... which has a useful utility in step 2: https://www.zen-cart.com/tutorials/index.php?article=82
