Drupal 8.x

We were playing with limiting HTML for editors and some pages seemed to be stripped of temporarily illegal tags and others the tags came back without intervention when the tags became legal again.
Were pages that were saved while something was illegal stripped of the HTML tags and pages that were not saved merely filtered?
This is just a guess.
We have a development site and thankfully that's the one that's broken.
I've only been doing Drupal stuff for a couple of months so.... hi

Taking Bootstrap theme as an example, I receive the following error after either entering a download URL or selecting a local zip file (I receive the same error installing any modules too):

An AJAX HTTP error occurred.
HTTP Result Code: 404
Debugging information follows.
Path: /core/authorize.php/core/authorize.php?batch=1&id=10&op=finished&op=do
StatusText: Not Found
ResponseText: No input file specified.

The Path entry seems wrong:  /core/authorize.php/core/authorize.php

Any ideas welcome!

Hi All,

I have created a form using webform in Drupal 8. Using handlers I have set email notification also.The content of email was well styled with htmls /css and images. Initially mail was coming fine as I provided in the body, after few days when I checked , email body is not taking the styles and  image (only plain text its taking not html ) that I set in the body of the email in webform even though i see the proper body content inside webform email handler section.

Can anybody suggest what could be a possible reason for this ?

Thanks

I'm not sure if I'm explaining this correctly in the title but it's all I can think of:  I have several columns in a Content Type that have a "x" if they have a certain amenity, or nothing if they don't.  But what I'd like, when I'm displaying the content, is to have an icon appear instead.

For example, let's say this is for a Content Type "restaurant" and I have columns for the type offered:  "red meat," "seafood," "vegan," "wheelchair accessible," "price range," etc.

Instead of an "x" for "Vegan" I'd like to show a vegan icon I've made.

In Drupal 7 catalogue could be created using views and panel (Views content panes). How create Drupal 8 catalogue using views, without using Ubercart and Commerce? I can't find the instructions. Please help!
