Description

get_icons() crashes on PHP 8.x when no API key is configured.

Cause

getActiveCurrencies() returns ['error' => 'API Key is not set...'] when API key is empty. The foreach loop then iterates over this error array, attempting string offset access ($crypto['code'], $crypto['name']) on a string value.

Severity

• PHP 8.x: Fatal TypeError (site crash)
• PHP 7.x: Warnings only
