Hello, when I go to Notifications section of my preferences, I see a red link where it is written "Set an email address", When I click on it, I go to https://lingualibre.org/index.php?title=Special:ChangeEmail&returnto=Special%3APreferences%23mw-prefsection-echo. It is a page on which one reads
No such special page
You have requested an invalid special page.
A list of valid special pages can be found at Special pages.
Return to Special:Preferences.
We have two choices.
Either it is not possible to receive email for notifications. If so , we should disable this section of the preferences so that no user arrive on a page that does not exist
Or, we need to fix the website so that Special:ChangeEmail does not point to a non-valid page.
