Issue with Universal Viewer

[canticods]

Hello,
I followed the documentation and this tutorial in particular to view images with the Universal Viewer inside a test omeka page. The universal viewer div is shown, but it’s blank. The console error shown is:

Failed to load resource: the server responded with a status of 500 (Internal Server Error)
new-photographs:1 Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0

What could be the issue in this case?
Thank you in advance

For us, we ran into a blank screen/JSON issue when loading Font Awesome via their JavaScript kit. After removing FA, UV started working. You might check for any JS that might be causing a conflict. Another time, we resolved an issue by completely removing the UV plugin from the Omeka directory and re-downloading.

Thank you, I’ve tried both but without success. I’m just guessing, but it could an issue related to some errors in the item definition. I’ll try again!

Here, a 500 error means it’s a backend issue. Do you have log for it?

Try add a “#” to your url: /uv.html#?manifest=
