 * Hello,
 * I have a problem that appeared on my site lately. The calendar doesn’t load, 
   I get a message
 * > Uh oh. We ran into a problem: Error loading API
 * . In the console I see a following error `GET (...)/wp-json/ssa/v1/getApi.php
   404`
 * My WP is up to date, your plugin is at version 1.5.8.3, running an Nginx server.
 * The Support tab of the plugin is all green checks, however the debug log shows
   this:
 *     ```
       The following is logged from update_debug_mode()
       in (...)/wp-content/plugins/simply-schedule-appointments/includes/class-developer-settings.php line 158:
   
       ... apply_filters()
       in (...)/wp-includes/class-wp-hook.php line 307:
   
       ...... do_action()
       in (...)/wp-includes/class-wp-hook.php line 331:
       [2022-10-10 13:53:00] $config_transformer
       ```
   
 * Interestingly, I have a development version of the site with the same setup (
   hidden behind a VPN) where the problem doesn’t exist.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-loading-api%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_
