 * just to narrow down the problem and help us debug the issue is it possible to
   try the following temporarily:
 * – deactivating all other plugins to see if this resolves the problem. If this
   works, re-activate the plugins one by one until you find the problematic plugin(
   s).
    – switching to the default theme to rule out any theme-specific problems

 * Hi,
    in wp-fullcalendar.php change **any function** in **public static function**.
   Example:
    - `function init()` –> `public static function init()`
    - `function enqueue_scripts()` –> `public static function enqueue_scripts()`
    - …
 * Idem in wpfc-admin.php

 * Same error, can we get an update to the plugin to resolve this?
