try this:

Go to the Get Reviews page first and download the reviews. Once they are showing up on the Review List page, then go to the Templates page and create a new review template. After you save it, there will be a shortcode button on the right. Copy the shortcode and paste it in a post/page or text widget where you want them to display.

For etsy it should be the shop url like so: https://www.etsy.com/shop/bjumuk/

What are the urls you are using? I will try them on my end.

Doug, looks like oxro.io is having issues. I just pushed out a Beta version of the plugin that should fix this. It uses your own server instead. You are welcome to give it a try. I did make a lot of changes in this newest version and it is still being tested. To get the beta version, go to the Account page inside the plugin, and look for the "Join the Beta program" check box. Then the update should show up.

You can add it to a reviewt template or a badge. For a review template look under the More Settings tab when editing a review template.

This should already be limited to jpg and png. Have you tested an svg file?

Try temporarily de-activing the cache plugin to see if that is indeed the issue.

Might take some custom coding to pull the reviews from the database. You could turn on the schema for the review template. Google should be smart enough to read both schemas on the page.

Okay good. It seems to be working then.
