PHP Warnings and Fatal errors after upgrading to PHP 8

[carlwhat]

Update: I'm using Ceon Manual Card 4.0.1 as well.

When I downgrade to PHP 7.4, the checkout process works again. These are the only 2 errors that hit in the logs:

for any number of reasons, i would strongly recommend against using a manual credit card module. you can try my module, you will not be disappointed:

https://www.zen-cart.com/downloads.php?do=file&id=2272

if you want to continue using this manual credit card module, you need to change lines 28 in:

includes/classes/class.ceon_manual_cardConfigCheck.php

and line 32 in:

includes/classes/observers/class.ceon_manual_cardSessionCleaner.php

i do not use the module but you need to rename the function to __construct. and continue passing any vars that are currently in there. ie:

//change to:

function __construct($var1, $var2) { 

there may not be anything where i have $var1 and $var2. but you need to change the name to __construct, which should resolve your error.

but again, i strongly recommend against using a manual credit card module.

best.
