 * Plugin version 2.3.0 causes the following error on every page load:
 * `PHP Fatal error:  Nesting level too deep - recursive dependency? in /wp-content/
   plugins/patchstack/includes/htaccess.php on line 39`

 * The cause for this problem seems to be in not using strict object comparison 
   in:
 * `/wp-content/plugins/patchstack/includes/htaccess.php on line 39` and 
   `/wp-content/
   plugins/patchstack/includes/activation.php on line 868`
 * `if ( $old_value == $value ) {` should probably be replaced with `if ( $old_value
   === $value ) {` to solve this, or, if strict comparison is not possible, some
   other way of comparing referenced objects should be used.

 * Hello, we have released a new plugin version that should fix this issue. We have
   swapped the logic around, so the values are only compared if options are updated
   relevant to the Patchstack plugin.
