I have exactly the same problem as Brad.
For me, bootstrap.min.css is loaded before dmxMediumEditor.css and dmxMediumEditor.js.
Nevertheless I have the problem.
Is there a solution here?
Check for errors in your browser dev tools console.
Does anyone have an idea why this is or am I reading the errors wrong?
you want to look under the console tab, not the network tab.
Here are the errors from the console.
The missing files (404) are in the specified folder. But the extension (.map) is missing.
How can I change this?
apparently the ending .css is replaced by .map, but why?
You can ignore the .map files warnings in the console. These are not errors and the .map files are used only for our own debugging purposes. No css files are being replaced.
And this has nothing to do with the actual error on your page.
Please provide a link where we can check this.
I checked your page but it’s actually quite a mess.
I see a lot of <html> and <body> tags on it. Not sure if that is your includes wrongly setup to include full pages or anything else, but that is wrong. You should only have these once, in the beginning of the page, not also here:
Another thing i notices your 3 modals are using the same input ids and names. This is also not right, your input IDs must be unique.
So fix these html structure problems and check again.
I had also added more body tags when inserting via Server Side include.
Removing these tags solved the problem
