I can't reproduce that problem locally. Could you check the Web Developer Console for errors please? (In Firefox's menu choose "More Tools", "Web Developer Tools").

Ok i just did some more tests and i can provide more details on how it happens. Here is an updated how to to perform this bug:

1. Compose a new mail
2. Erase any signature that might have been automatically inserted
3. Save it as a draft
4. Open it again, using the "Edit" button on the mail preview
5. Write at least one line of text and leave an empty line below that
6. Place the carret on that empty line
7. Click the Signature button to insert a signature on that line
8. The signature isn't placed

The Webdev console does show some things that could fit, but it's all in french sorry:

Sorry, I still cannot reproduce that. I made a screen recording of my attempt. Did I follow your steps correctly?

Screenrecording-insert-signature.webm

(The signature is also correctly inserted if I compose HTML emails.)

Thanks for trying to get through this with me @pabzm
So first off, when i create the new draft, i don't write anything in the mail Subject, neither into the Body. I just delete the signature.
Then, when i save that draft and get back to modify it, below the line into which i wrote text (where you wrote "test") i only create 1 new line, not more.
Finally, if this has any importance, the signature contains a picture. It looks like this:

Still can't reproduce. Is there another difference in the workflow?

Insert_signature_with_image.mp4

If not, I'm afraid your setup is to blame :/

The messages from the browser console seem unrelated to your problem.

Did you try to change you signature?

[Cwpute]

I can't read your video it seems :/

Here is the list of things i tried after your message:

1. Followed the steps listed above using another browser that has (Falkon) and it still doesn't work.
2. I created a new identity with a similar signature but it still didn't work:
3. I tried removing the picture in the signature, and it still didn't work:
   
4. Seeing that my original signature was always appearing first before switching to the second identity, i set the test identity to be the Default one, but it didn't change anything.
5. I create another identity with a signature that was not formatted in HTML, but it didn't work:
   
6. I created a third test identity with no HTML and no emojis that simply read yeah., but it didn't work. (if you wonder, this one was Aergia, godess of sloth)
7. And finally: i tried with an entirely different computer on the same account, and it still didn't work 😠

I've contacted the admins running my instance for further support, to see if there are variables i didn't take into account and if they can reproduce it themselves.

Hi 👋
Thank you for you support <3

We spent a bit of time trying to understand the exact path to follow in order to reproduce this bug.
Here are our findings :

• It happens on different browsers Chromium, Firefox (even in debugging mode, without the plugins)
• It also happens even after clearing the cache and sessions data
• It only happens on a particular account (we cannot reproduce it on other accounts, with the exact same parameters and signature)
• The faulty account was using the following non-default parameters, but reverting them manually did not solve the issue :
  • Attachment : RFC 2231 (Thunderbird)
  • MIME 8 encoding activated
• We face the same issue with and without the image in the signature, or with only one line of un-formated text or pure text (no HTML)

Here is a short video of the issue :

This issue is minor as there is a work around, but it might help others facing similar issues.

New input, here is the user's preferences value extracted from database, after trying to revert all the configuration to the default value, using the web interface.

When I revert it to the default configuration using SQL commands, the problem seem to disappear.

I currently have no good idea what the cause could be, sorry.

I'm leaving this open until something enlightens someone, and for future references.
