Unable to upload products to Website

Hi! I hope someone can help me with this. I am developing a drop-shipping e-commerce website and, since last week, I am no longer able to upload any product from Amazon, eBay, AliExpress, or Etsy to my website (www.shopping.tennis). When I try to do so, I get a pop-up message in the top left corner of my screen saying the following: “MOVED PERMANENTLY. The document has moved here.” I use the Wooshark Chrome extension and the plugin ‘TheShark Drop-shipping’ to upload products from Amazon & eBay to my website. Can you please tell me what to do to resolve this issue? Please note that all my WooCommerce files are up to date. Thanks, in advance, for your help.
