Can't add product to category after adding canadapost module

Hi,

I am building a new fresh webstore with zencart 1.5.6a, after adding canadapost shipping module plugin V.153-154created by Dr.Byte and when I try to add a new product I get an error zen_href_link('', 'cPath=1&action=new_product_preview', 'NONSSL'), my log file is clean.
This is the first module to install after my clean zencart installation.

The same module and version is working fine with my live site using zencart v.1.5.5f www.crystalstrass.com

Zencart software installed on my local machine using XAMPP

Any help would be appreciated.

Thank you in advance

I would hazard to say that the two are not connected at least if properly installed.

Some questions: what product type was attempted to be added?
Was a product attempted to be added before incorporating the plugin?
What files are currently different from a default install?
What is meant by the log file being clean?
What database is being used in this install? Was it upgraded using zc_install and in reviewing such are you able to modify configuration settings or do you get an error?

Hi,

It was a cleen install and clean database, I created a category and then added one product, it shows fine
Adding canadapost modulle will show this error when you try to add another product or edit the existing one.
Then I redid again the test and reinstalled again a clean version with a new clean database zencart 1.5.6a here I was able to create new category as with the first test but was not able to add a product, same error as my snapshot
Note: - zencart 1.5.6a clean install
- new database, no upgrade
