@alwayspaws You need the original file classes/product.php file that is in the 1.01 release and the AdminImportController.php file that was corrected the end of May. From the errors you were having I am guessing that you have both of the files that were corrected the end of May, so you just need to replace the Product.php one. You can get it by downloading the file from here, unzipping it on your computer and then uploading just the classes/Product.php file to your site on Siteground.
