About Debug Bar Localization
From the official readme · v1.1Description
Debug Bar Localization adds a new panel to the Debug Bar which displays information on the locale for your install and the language files loaded.
Additionally it will show you:
- The installed languages.
- Which text-domains were called from translation functions while no
load_..._textdomain()call was found for that text-domain. - For which text-domains
load_..._textdomain()was called more than once. - Which files WP tried to load to obtain a translation and whether this was successful.
- If successful: how many translated strings were found and when the translation was last updated.

Changelog
Upgrade recommended. WP 4.5 compatibility & some bug fixes and enhancements.
1.1 (2016-04-29 )
- [Enhancement] Don’t show warning about duplicate load calls on plugins page as that’s caused by core, not by a plugin and the warning could be misleading.
- [Enhancement] Make loading of ‘our own’ text-domain compatible with use of this plugin in the
must-useplugins directory. - [Enhancement] Improve categorization of the loaded text-domains. This mainly applies to text-domains for which the mo_file paths are being filtered.
-
[Enhancement] Added a section showing potentially unnecessary/inefficient
load_textdomaincalls. -
[Bugfix] The plugin loading order functions were inadvertently checking the wrong value and – in single site – install, adding an invalid value to the active plugins list causing incorrect ‘plugin deactivated as file not found’ notices.
-
[Compatibility] Fix WP 4.5 compatibility – the check whether a text-domain
loadcall was made (ab)used a bug in theis_textdomain_loaded()function. This bug was fixed in WP 4.5. Fixed by creating a work-around to still be able to provide this information. - [Compatibility] Prevent PHP error notices in WP < 4.0.
- General housekeeping
1.0 (2016-01-13)
- Initial release.
