    When clicking the ‘Refresh URLs’ button in the settings, wordpress crashes with a Fatal error.

    Debug logs show:

    [17-Sep-2025 07:53:21 UTC] PHP Fatal error:  Uncaught Error: Undefined constant “__CLASS_” in /home/<redacted>/domains/<redacted>/public_html/wp-content/plugins/cal-embedder-lite/cal-embedder-lite.php:814

    Stack trace:

    #0 /home/<redacted>/domains/<redacted>/public_html/wp-includes/class-wp-hook.php(326): Wp_Cal_Embed_Lite::validate_settings()
    #1 /home/<redacted>/domains/<redacted>/public_html/wp-includes/plugin.php(205): WP_Hook->apply_filters()
    #2 /home/<redacted>/domains/<redacted>/public_html/wp-includes/formatting.php(5119): apply_filters()
    #3 /home/<redacted>/domains/<redacted>/public_html/wp-includes/option.php(887): sanitize_option()
    #4 /home/<redacted>/domains/<redacted>/public_html/wp-admin/options.php(344): update_option()
    #5 {main}
    thrown in /home/<redacted>/domains/<redacted>/public_html/wp-content/plugins/cal-embedder-lite/cal-embedder-lite.php on line 814

    The cause is a misspelled constant on line 814: __CLASS_ should be __CLASS__
    After fixing this bug, the button no longer causes an error.
