Plugin not working as expected on live site, but works on local install

Hello,

I love your plugin thank you for all the work with it.

However I have ran into a strange problem, where the plugin works normally when I have the site installed locally via Local, but for some reason on the live website it fails to actives and just opens the file directly with no lightbox.

I am storing the files on a statis subdomain, but the local install also points to those files and there it works. I also tested adding the static subdomain on the CND field, but still no luck.

Please let me know if you can help me figure out what is causing this problem.

Thank you in advance for your time and help on the matter.

You disabled element inspect, right click and view source – under these circumstances I can’t help you, sorry.

Edit: at least I need to be able to use the element inspector of my browser to check what is going on on your site.

All I can see is that the images are not recognized at all by the backend.

I did a quick test with the source code of your page on my local test server – if you set https://static.domain.example as CDN url you must also have the images accessible locally using your site URL combined with the remaining URL of the image.

Example:

Your website is https://www.domain.example.

Your image is https://static.domain.example/2021/05/some-image.jpg.

The CDN URL is https://static.domain.example.

The image must now also be available at https://www.domain.example/2021/05/some-image.jpg to be recognized as valid image. However this is not the case on your site. You server images from a static domain but they are not available at the same URL from the real domain. Even adding /wp-content/uploads would not work.

It looks like you don’t have any image available on the real domain at all.

I don’t know your exact setup – but the problem is caused by the fact, that the images are only visible on the static domain but not on the real domain.

For example see my test page:

https://wordpress-demo.arnowelzel.de/lightbox-with-photoswipe/

The images are served using JetPack but are also available on the site:

CDN URL: https://i1.wp.com/wordpress-demo.arnowelzel.de/wp-content/uploads/2019/01/Berlin-2017-01-29-10.jpg?ssl=1

Site URL of the same image: https://wordpress-demo.arnowelzel.de/wp-content/uploads/2019/01/Berlin-2017-01-29-10.jpg

So what Lightbox with Photoswipe does: it will replace the CDN part “https://i1.wp.com/wordpress-demo.arnowelzel.de” with the real domain “https://wordpress-demo.arnowelzel.de” and then check if the image is available. I hope you get the idea.

Yes thank you! You have validated my suspicions, I will dig more into this one I have a clue now where to troubleshoot.

The images are served from a subdomain indeed, the strange part is that an exact mirror of the site locally still points to the static domain for the pictures, but the plugin works with no issues.

However the solution is to remove the forwarding and update the database path of all images to point to the main domain. I will try to find a workaround and will post if I do, if not at least we know now this setup does not agree completely with the plugin.

Thank you very much for the time and help on the matter.

Removing the static domain removed the problem and everything works perfect.
