PHP 8.2 Fatal error

Dobrý deň,

pozdravujem výrobcov a ďakujeme za super plugin,

po aktualizácii e-shopu z PHP 7.4.33 na PHP 8.2.5 mi začalo vyhadzovať error

PHP Fatal error: Uncaught TypeError: strtotime(): Argument #2 ($baseTimestamp) must be of type ?int, string

a prestalo generovať štítky.

Skúšal som dať nižšie verzie PHP 8.0, 8.1 ale až keď sme dali naspäť 7.4 tak to znova prešlo a štítky vygenerovalo.

Prikladám error z logu:
