PHP Warning: Undefined variable

I recently upgraded from 1.5.7d to 1.5.8a and everything is working beautifully - however I am receiving the following DEBUG logs.
Since I am not a programmer - I was hoping that you could provide a snippet that I can add to these pages that will declare the variable and satisfy php to stop the log files.

Zencart 1.5.8a / PHP 8.0
website: https://www.d a n i e l w a l t h e r s.com/dwstore


PHP Warning: Undefined variable $category_depth in /includes/languages/english/responsive_classic/index.php on line 29.
PHP Warning: Undefined variable $category_depth in /includes/languages/english/responsive_classic/index.php on line 46.
PHP Warning: Undefined variable $category_depth in /includes/languages/english/responsive_classic/index.php on line 50.

and also:

PHP Warning: Undefined variable $address_arr in /includes/modules/payment/paypalwpp.php on line 1744.

Any help will be greatly appreciated.

The file

includes/languages/english/responsive_classic/index.php

should not be present on a site running 1.5.8a. This is an older style language file.

Oh dear!! I see what you mean. Thanks so much for pointing this out.

And if an older file was still present, may want to consider what other older files might remain. Easiest to figure out if can determine why that offer file was present. Might just be the one, might not. :unsure:

currently getrting the $address_arr error with 2.0 install. Says line 1740 in 2.0

Since it was not addressed here, any thoughts?

Please open a PR and change this check from

$address_arr == FALSE

to

empty($address_arr)

includes/modules/payment/paypalwpp.php line 1740

master or 2.0 or both

Use 2.0 for bug fixes. (Core committers will merge it into master after updating 2.0.)
