Created attachment 109220 [details] Both options are selected, but message still dispayed w/o html and images. All messages in preview area displayed w/o html format (this is ok). For some selected contacts I chose "Show html format" and "Load external reference". But this is not affect at all. I know, that I need reselect message, to this changes start to work. Or (for some contacts) it do something one - show html, but don't load external references. This items works fine in previous version (kde-base/kmail-4.14.8), that I've used.
While I could reproduce this issue with KMail 5.5.2, nowadays it seems to work correctly with KMail 5.9.2 (Qt 5.11.2 / KF 5.51) as well as KMail 5.14.40 (Qt 5.14.1 / KF 5.69). Therefore closing the bug. If at all, there might still be an issue with remote address books, see Bug 377554.
No, this bug is still reproduced on updated system: linux kernel 5.4.28 KMail Version 5.13.3 (19.12.3) KDE Frameworks 5.67.0 Qt 5.14.1 (built against 5.14.1) The xcb windowing system

I can't reproduce it here. It works fine in last version.
May this be related to some configuration files in ~/.config/ or other hidden folders?
As you can see from your screenshot, viewing HTML was fixed indeed, compared to your original report. Only loading external images still seems to fail for you. That being said, I tested this again with the current git version as well as with KMail 5.13.3 by inserting "<img src=https://localhost:8080/image.png>" in a new mail and serving said image with "python -m SimpleHTTPServer 8080". After toggling "Load external..." from the contact's context menu I could observe the GET request and the image displayed fine. With the git version, even reloading the message was not necessary, just like it should be. I would suggest to: - wait for KMail 5.14.1, which has lots of related fixes - check whether external images load at all, i.e. when the global option for that is turned on - turn off KMail's ad blocker - test with a separate/new local user account on your machine, i.e. check with a fresh KMail/Akonadi config - test if another application is able to show the image, e.g. Thunderbird (to rule out a broken webserver). If this still does not work in KMail, please file a new bug with clear steps to reproduce and most importantly attach the broken mail as an mbox file. > May this be related to some configuration files See fourth suggestion from above on how to test this easily.
