PHP Fatal error: Uncaught TypeError: in_array()

Hi Mike,

I use your plugin for ages without problems at all my sites. Thank you!

But now I installed it (v.5.0.4.2) on new one (WordPress 6.1.1, PHP8.0.22, MySql 8) and got the following errors:

As I can understand it fails in External Links->Settings->Advanced, due to there is not ‘Save Changes’ button and message:
