Create a css class for Image field in Views
In Views, when adding an image field there's no way I can add a css class to the image tag. For example, if I were to shape the image to a circle using bootstrap I have to add a .rounded-circle class to the image and I couldn't find a way to do it. So I think it's conveninent and important to have such function added to the views.
<img src="cinqueterre.jpg" class="rounded-circle" alt="Cinque Terre">
Here just a sample I imagine how it would look like or something similar. Please consider. Thanks!

Thanks, the /tmp folder was the problem. I moved it elsewhere and then the updated worked. Thanks again!

Probably not the reason, but worth to do a quick check: Sometimes the update cache interferes, so if something's odd with updates - some module (or core) claims to have updated, but then...

Nope, not touched any permissions!
