Edit View: opening Format Settings will result in ajax error instead of opening the settings overlay

Otherwise, thanks for all the excellent work on this module, it really makes life a lot easier!

Why ar you posting this here, in the Geofield Map module?
and why did you set this as Major Bug.
There is nothing in your description that related your issues to the Geofield Map module and that prove that you have found a general bug in this module.

Everything looks much related to your personal Drupal setup/use case, and not clearly caused by a bug of the Geofield Map module.

I am closing this as "Cannot reproduce".
Feel free to re-open but only providing clear details your issues are caused by the Geofield Map module, and mark this as a Bug ONLY if you have and cabn give clear evidence of that ...
(if something doesn't work on your side it is not given it is a general bug in some module ... especially if no body else is reporting a similar issue).

I thought it was an error because it only appears once I set the the Views Format to "Geofield Google Map". Once I do this, I am no longer able to open the Settings panel, as I stated above.

But nevermind, I found a workaround. Not sure if the problem still persists.

Sorry for bothering you and thanks for the good work on the module.

No problem @ProperCroc ... you didn't bother, and is always good to report your own issues, if you need support.
Only thing is not to mark them as Bug just because something doesn't work as expected in our own environment.
Reporting a Bug needs some more detailed documentation and evidence of it, that it could apply on a specific use case but on a general (reproducible) basis. Otherwise it is just a Support Request.

I strongly suggest you to further inspect you scenario, and try to better / properly get what and why was happening to you.
Proper debugging (and mostly with xdebug in this PHP/Drupal context) is one of the best ways to improve your Drupal coding skills and tech control of your web app.

Just wanted to add in case anyone runs into this. The Claro admin them was the issue for me with the Map format in Views. Switching themes allowed the ajax to work again.
