Unknown Error in Currency.php

[johnsma2000]

Not sure how to fix this issue or what to do to fix this but I have tons of this entry in my error logs.
2024-03-25 13:08:20 - Unknown Error: AbanteCart core v.1.3.1 Unsupported operand types: string * string in <b>/XXXXXXX/currency.php</b> on line <b>228</b>

How do I fix this?
Any help is appreciated.
Thank you

Hello.
Make sure your php version is 7.3 but the preferred solution will update your AbanteCart
