Those three fields are MxChat settings stored as WordPress options. MxChat doesn’t register them with WPML automatically, so they won’t appear in String Translation on their own — but you can add them in a couple of minutes with WPML’s admin-texts feature:
- Go to WPML → String Translation.
- Scroll to the bottom and click “Translate texts in admin screens”.
- Find
mxchat_options in the list (use the search box) and expand it.
- Tick the fields to translate:
intro_message (Introductory Message), top_bar_title (Top Bar Title), ai_agent_text (AI Agent Text), plus any other label fields you use. Click Apply.
- Back in String Translation, the strings now appear under the domain admin_texts_mxchat_options. Add the translation for each of your 3 languages and mark them complete.
Notes: save the English text in MxChat first (WPML translates from that base value). This admin-texts method covers settings-stored strings like these three; a few hardcoded plugin strings are handled by the plugin’s translation files (Loco Translate / WPML localization) instead.
