The plugin does not work in wordpress in the Zino theme. When opening a PDF, a lightbox opens with a gray background. That's all.
If you switch to the "Iframe" mode, it works in the desktop version, but does not work in the mobile version.
If you install an older version, it works with some documents in the desktop version, but it definitely doesn't work in the mobile version.

I have experience using it on another topic - everything is fine, I even wanted to donate. But I ran into this problem. There are 3 sites with your plugin ahead.

Hello,

Is it possible to see the problem anywhere?

aktiv-uk.ru/documents/

I tried version 1.3.13 and version 1.3.18.
They behave differently in different browsers and with different documents.

For example, microsoft edge desktop now opens all documents per page.

Some of them don't open in yandex browser.

It doesn't open any documents in Firefox.

The situation is similar in mobile browsers. Some documents are opened, and some are not.

The PDF was reassembled by different applications. Including microsoft print to pdf.

On another site this is not observed at all, version 1.3.13 is there, I'm afraid to update.

Could this be due to the fact that the pages are https and the files are on Http?
But I make links by type /documents/.... pdf
Without the domain part of the path

This issue has been resolved. It didn't help. Some documents are opened, and some are not.

Make sure MIME type for *.mjs files is configured properly on your server. It should be text/javascript instead of application/octet-stream.

You contact hosting/server support ask this question.
