Good day!
As the title says the Media Gallery in a lightbox slideshow that is connected to a database is working on preview mode but at the live site it is not moving at all.
I am always having this error when running on Preview Mode.
Failed to get data from (new) server: SyntaxError: Unexpected token < in JSON at position 0
I am not sure where it is from since there is no line error on the codes.
Thanks.
Have you synced your dataset from the sandbox to the live?

Also, his error normally happens when you make a request to the server and parse the response as JSON, but it’s not JSON. If you’re using JSON.parse directly, that’s a plain old synchronous call and you can replace the call with a console.log to see what’s going on.
The actual request worked fine. It got a response. But the res.json() is what failed. JSON should start with a valid JSON value – an object, array, string, number, or false/true/null. This response started with a < (hence the “Unexpected token <”).
That unexpected token, <, is a strong clue that the response was HTML instead of JSON. The root cause is that the server returned HTML.
Have a read here.

Looking in the forum, I have noticed another forum user who has posted the same issue as yourself here.

So please keep an eye on this other post and see if it is not an issue with your code and is actually an issue on Wix side.
Thanks, Yes mine was also perfectly working the first time I tried it but the error showed up so I was actually thinking it caused media gallery slideshow to stop at live too.
