I have a content type with an editable fields field. I've given permission to the anonymous user to edit it (no autosave AJAX). However, if I create a view that includes this field (formatter editable fields), the anonymous user can edit the field. However, if I return to the view or refresh, the following error appears:
The website encountered an unexpected error. Try again later.

So, on our Drupal 10 site, any audio file gets rendered with an additional source closing tag, like <source src="/…/name.mp3" type="audio/mpeg"></source>. The closing </source> is not valid HTML.
There is no closing </source> in our theme. If I change the theme to Claro, the closing </source> is added as well.

Currently on Drupal 10.5.6. Prepping for update 11.1

I use apache2 and caddy.

The caddy conf-file for the website reads:

I thought this could be simple; however I am doing something wrong.

On my site I have many content types, like prose, poetry, recipes, events etc. I created a block showing latest recipe added. I want this block to appear in right column on all content types except recipe itself. This was possible via admin UI. (I checked check-boxes for all content type except recipe) However after doing this this block won't appear on the <front> page.

So how to achieve this? In short, i want,
