Hey @luis5791, I’m just another user like you. But I fail to recognize your issue. I’m a PRO user myself.
Could it be that the thing you don’t mention, is that you probably tried adding a QR code as an SVG file? You have to allow uploading SVG files in the settings of Elementor. Here is the official support documentation for SVG uploads.
… BUT THINK TWICE THOUGH BEFORE YOU UPLOAD SVG
Uploading SVG’s can pose a security risk, not matter what software you use to create a web site. Exporting your QR code to a .png file and then place it in your site is a lot safer.
I am aware that your post is already 2 months old, but my response is also for other people who might get discouraged by this undeserved lousy review.
Cheers,
Anne
