Wicecat Module and Modifying headers.

WICECAT MODULE AND MODIFYING HEADERS

. I'M HAVING DIFFICULTY WITH THIS MODULE AND HAVEN'T BEEN ABLE TO GET MUCH IN TERMS OF ASSISTANCE FROM THE DEVELOPER ACCEPT THAT I NEEDED TO COMPLETE CLEAR OUT AND REINSTALL EVERYTHING. SO I DID; TWICE. DURING THE RELATING OF CATEGORIES OR EVEN TRYING TO IMPORT PRODUCT INFORMATION I'M GETTING THE FOLLOWING ERRORS LISTED BELOW. WHAT IS CAUSING THIS AND HOW WOULD I GO ABOUT FIXING SUCH. ITS ON THE NEW VERSION OF PRESTASHOP 1.6.10 WHICH DOESN’T SEEM TO BE THE ISSUE.
