Each time the user logs in, their preference settings are reset.

Issue

note
This issue occurs when the language pack is installed due to the save() method on line 155 in the file core/backend/UserPreferences/LegacyHandler/SetUserLanguage.php.

Each time a user logs in, the system executes a function called saveFormPreferences, located in the file public/legacy/modules/Users/User.php. This function expects the $_POST variable to contain certain user preference settings. However, the $_POST variable arrives empty, causing all user preferences to reset to hard coded values upon every login.

The affected preferences include, but are not limited to:

mailmerge_on
user_swap_last_viewed
user_swap_shortcuts
use_group_tabs
sort_modules_by_name
user_subpanel_tabs
user_count_collapsed_subpanels
user_module_favicon
no_opps
timezone
ut
use_real_names
mail_smtpauth_req
mail_smtpssl
gsync_ca

This issue is critical as each login erases important user configurations, such as their customized timezone. This can significantly impact.
