Secondly,
Any new item added in the admin panel does not appear in the shop. I have to copy/duplicate an old product and after change the description to create a new article. When I duplicate the product or create a new one from scratch, in the admin panel all the blank spaces to complete the info are filled with " (") " Also as the article appears in the shop, when you choose a variant immediately in the display of the products, it sends you to a blank page.
For each problem, I attach an image
Thanks everyone.
You use a WYSIWYG editor to edit the CMS texts. When saving, it happens that the Smarty syntax -> is replaced by ->. Then the shop can no longer process the CMS text. Please check in a plain text view whether the syntax fits. The HTML view of the editor cannot show the error.
