Fix WPML Compatibility Issue with Event Bubbles Revert

[Akhill2020]

Summary by CodeRabbit

• New Features
  • Added multilingual compatibility: calendar AJAX requests now include the current language when available (WPML), ensuring language-appropriate data.
• Bug Fixes
  • Improved resilience of tooltips: failures during tooltip initialization no longer break calendar rendering; errors are safely logged.
• Documentation
  • Updated shortcode reference to use [simple_calendar] for embedding calendars.

Walkthrough

Adds WPML language propagation to AJAX requests and localized script variables, updates shortcode name in documentation, and wraps qTip2 initialization in try-catch. JavaScript now uses shared ajaxData for grid/list navigation and includes lang when available. PHP appends lang to admin-ajax URL and exposes wpml_language to scripts.

Changes

Cohort / File(s)	Summary of Changes
Documentation update CLAUDE.md	Replace shortcode reference from "[calendar]" to "[simple_calendar]".
AJAX data + tooltip handling assets/js/default-calendar.js	Switch to shared ajaxData for grid/list navigation; include lang when available; add try-catch around qTip2 initialization; keep existing behavior for positioning/show/hide/render.
WPML var localization includes/functions/shared.php	Inject wpml_language into localized JS variables when ICL_LANGUAGE_CODE is defined.
AJAX URL language support includes/main.php	Modify ajax_url() to append lang query parameter when WPML is active; otherwise return base admin-ajax.php URL.

Poem

A hop, a skip, a multilingual spin—
Calendars whisper, “lang” tucked in.
Tooltips behave (we try, we catch),
Dates align, a perfect match.
From grid to list, I thump with cheer—
Simple hops, clearer days appear! 🐇📅

Pre-merge checks and finishing touches

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Title Check	⚠️ Warning	The title is confusing and does not clearly convey the main change because it awkwardly combines “Fix WPML Compatibility Issue with Event Bubbles” and “Revert” without explaining what is being reverted, and the summary changes do not actually perform a revert, making the title misleading and unclear.	Rename the title to clearly reflect the actual change, for example “Restore WPML compatibility for event bubbles” or “Add WPML language support to event bubble AJAX calls,” so that it clearly and concisely summarizes the main update.
