 * Hi guys,
 * Been having issues all of a sudden – the Visual editor in the backend changed
   font color to white and it doesn’t display visual elements any more – just html.
   Any idea what might be causing this? [https://prnt.sc/m09wmd](https://prnt.sc/m09wmd)
 * p.s. I tried with disabling all the other plugins but that didn’t help…

 * Hi Petar,
 * It seems there’s a conflict somewhere… When you disabled all the other plugins,
   did you only keep our core plugin (The Events Calendar), or did you also have
   some Events Calendar extensions enabled? (and if so, which ones?).
    Could you
   try to switch to the default theme (Twenty Seventeen for example) and tell us
   if that makes a difference? For more information, you may read our [documentation about Testing for conflicts](https://support.theeventscalendar.com/303643-Testing-for-conflicts#look-for-solution).
 * Please let us know how it goes.
 * Cheers,
    Jeremy

 * Thank you for the quick reply Jeremy!
 * The Calendar is the only active plugin and I have switched to the Twenty Nineteen
   theme but the issue is still there.
 * Switching to a different plugin like Modern Events Calendar gives the same thing
   in the backend Editor… which is quite weird!

 * Hi Petar,
 * Since you still had the same problem with only The Events Calendar and Twenty
   Nineteen, it might be a cache issue. Could you clear all your cache, including
   your server cache and [your transients](https://wordpress.org/plugins/transients-manager/)?
   
   Could you also make sure your WordPress and The Events Calendar are up-to-date?
 * Cheers,
    Jeremy

 * There is no caching anywhere. Did you mean clear the unused transients because
   those are cleaned…
 * By the way, enabled the Debug mode and getting the following error:
 * Undefined property: stdClass::$plugin in /home/trave371/public_html/wp-includes/
   class-wp-list-util.php
 * And that is the corresponding code in class-wp-list-util.php
 * /*
    * This is simple. Could at some point wrap array_column() * if we knew we
   had an array of arrays. */ foreach ( $this->output as $key => $value ) { if (
   is_object( $value ) ) { $this->output[ $key ] = $value->$field; } else { $this-
   >output[ $key ] = $value[ $field ]; } } return $this->output; }
 * Cheers,
    Petar

 * Finally figured out what was causing that error – the .htaccess file in the wp-
   includes dir
 * # Restrict PHP File Execution
    <Files “*.php”> Deny from All </Files>
