Error on PHP 8.0

[kimipooh]

WP-FFPC 1.11.2 does not work with PHP 8.0.

How to fix as follow:

wp-ffpc-class.php 1016-1018 lines

[Before fixed]

	public function plugin_options_migrate( &$options ) {

		if ( version_compare ( $options['version'], $this->plugin_version, '<' )  ) {

[After fixed]

	public function plugin_options_migrate( &$options ) {
		if($options === false) $options = array('version' => '0.0');
		if ( version_compare ( $options['version'], $this->plugin_version, '<' )  ) {

This is caused by the

wp-ffpc-abstract.php From line 514 public static function _get_option ( $optionID, $network = false ) {

In _get_options( $optionID, $network = false ), the return value $options has several patterns such as false (bool value), array, etc. When installing for the first time, the WP-FFPC setting does not exist in the database used by WordPress, so the value of $options becomes false (bool value).

Then the following $options['version’] (public function plugin_options_migrate in wp-ffpc-class.php) ) will not exist ($options = false), and the first argument of version_compare will be false. However, since version_compare expects a string as an argument, a type mismatch will occur, and as of PHP 8.0, it is an error to do so.

Please fix the issue.
