Hmm something is not right with jQuery on your site, but I’m not sure what exactly.
Your best bet is to try switching to one of the default themes such as Twenty Seventeen and see if the error disappears. If so, you should contact the author of your theme and let them know about the problem.
Alternatively, the problem might lie with one of your plugins. Try deactivating each of them one by one to see if the error disappears.
Feel free to post a screenshot of the appropriate section of Query Monitor here and I might be able to give you some more help.

Don’t see an upload here.
Here is a link to a screenshot: Dependencies jquery
The blog is based on a child theme to twentytwelve I did myself quite a while ago. There might be some plugins causing this, but I to disable all of them might disturb my readers and I don’t have a dev copy yet. So it would be helpfull to find the cause of the problem and I might be able to change only that part.

On the preview with other Themes, Query Monitor showed the same error.
Thanks for the screenshot. From that, I can’t tell why QM is highlighting jquery as having a broken dependency. It might be a bug in QM, or it might be that a plugin is doing something that QM hasn’t accounted for.
Are you able to send over a list of all the plugins that are active on the site?

I did deactivate the three listed ones. One by one, deactivate, QM again, activate again.
These were:
– WPPA (WP Photo Album Plus)
– Mailpoet 2 (that’s the wysija-*)
– Cookie Notice
Problem was still existing.
The reason might not be the Theme either as I did change it a few days ago. Problem existed with the old Theme.
I know there is something weird in my installation and QM was my hope to find it.
Two more “problems” that might be involved in the same reason:
– the build in editor jumps to the end of the page if I try to add a link
– the plugin update never comes back on its own (admin page, not the one in installed plugins – that is fine)
BTW: Switching off heartbeat gives an error as well (admin pages, wp-auth-check)
Can you try deactivating the “Better WordPress Minify” plugin to see if the issue disappears? From your list, that’s the only one that looks like it could cause a problem.

Good guess! You are correct. Disabling BWM did resolve the problem. But at the end is not a final solution. I did try to exclude some of the JS from the minify process (there is a exclude option per file). I did try with those:
jquery-core
jquery-migrate
jquery-form
query-monitor
But this did not help. Is there any way I can find out with QM which one(s) to exclude? I did try some other plugins that did not give me the best solution (and other problems) as well.
Thanks, I’ll see if I can find some time to check it out and find out whether the bug is in QM or in that plugin.
For now, I think it’s safe to ignore the error that QM shows you.

Stop research. It was a problem in the Plugin (or my kind of configuration I did). After using another one for Minify JS and CSS everything works fine – no more errors.
