Lost fast checkout page while trying to configure extension

[thatguy]

As stated I lost my fast checkout page on my website after configuring my authorize.net extension. I wasn't able to take a payment so i was on the phone with tech support and after failing to find any error on their end I went back to the storefront page of my website to try the checkout again and the fast checkout page wouldn't show.

Things Ive tried:
Clearing the cache
Restarting my computer
a different browser
making sure everything is as it was to the best of my knowledge

I figured out how to turn error logs on and this is the error I'm getting

Unknown Error: AbanteCart core v.1.3.3 Unsupported operand types: string + float in <b>/home/loveyou7petsuper/public_html/core/lib/tax.php</b> on line <b>228</b>

you can try to downgrade from php8 to php7.4 to solve an issue.
