I'm trying to do the same thing as #96
Editing the config.js seems to have no effect.
//{ name: 'styles' },
{ name: 'colors' },
{ name: 'about' }
commenting out the styles toolbar doesnt remove it on the wysiwyg field.

Intentionally making a syntax error does not produce an effect either. Where does the config.js get loaded?
Also getting this error. Have not been able to figure out the source.

Using Chrome Developer tools, it seems that the config.js may be being taken from:
https://A_URL/vendor/backpack/ckeditor/config.js - it may have a ?t=XXX appended which I suspect is elixir or some sort of cache busting mechanism.
Check what is returned by that (where A_URL is relevant to your setup) and use http or https as appropriate?
Also, Chrome caching might have changed in the past months - it's been particularly painful lately to do hard refreshes. Try seeing if your config.js changes appear in an incognito window. Just a thought.
I switched to summernote because the default settings where what i wanted. I did not think about the cache thing. That was most likely my problem
I had the same issue - config was being cached and couldn't figure out how to make it refresh. Opening the config file in the browser and hard refreshing then reloading my admin page worked. https://stackoverflow.com/a/40129371/5623108
