Fatal error in 8.1.3+ – footer_text():

Hi,

After updating Image Regenerate & Select Crop from 8.1.2 to 8.1.3 (also tested 8.1.4), the site crashes with a fatal error in wp-admin

• Plugin version:
  • 8.1.2 → Works fine
  • 8.1.3 → Fatal error
  • 8.1.4 → Fatal error

It appears that the method:

public function footer_text(string $original)

does not handle null values. WordPress sometimes passes null to the admin_footer_text filter, which causes a TypeError in PHP 8+.

Suggested fix:

public function footer_text($original = ”) {
$original = (string) $original;
}

or

public function footer_text(?string $original = ”)

This would restore PHP 8 compatibility.

Please advise.
Thank you.
