Thank you so much @Linux-Is-Best! 

In your AdminCP (administrator control panel), if you search for the phrase "custom," you can customize the error pages and message. You'll have used to the full editor when doing so, so you can be as creative as you would on a forum post.  But if I understand you correctly, you wish to give people a tease or sneak peek of what they are missing out on.  Unfortunately, that would be beyond the scope of the core features and require an add-on. The whole point of denying permissions is for people not to know what is behind the closed door.
I could not locate such an add-on. But there is a business listing of available developers who are available to hire if you are interested in having one created.   https://invisioncommunity.com/third-party/providers/

Good evening,

Now resolved 🙂 Thanks to this message available on Google! I advise you to read it: https://www.invisionboard.fr/forums/topic/65465-dates-disparues-sur-certains-posts/

Subject related to version 4.4.3 of Invision Community.

Apparently still relevant and congratulations to translators of IPS languages.

Thank you all,

It is in Icons and Logos:

Second option. If it's weirdly cropped then most likely its not sized correctly. I believe it needs to be a square and 512x512 minimum, suggested is 1024x1024 IIRC.
