wp-cassify issue with php 8 – white_list bugged

Hello,

I have the same problem than others in this forum when upgrading from php 7 to php 8 with wp-cassify 2.3.1  : wp_cassify_is_in_while_list returns always true and there is no more redirection to CAS Authentication after upgrading php to >= 8.

By the way, note the typo in while_list (means white_list).

The issue comes from the line 1144 :

if ( strrpos( $url, $white_url, -strlen( $url ) ) !== false ) {

The behavior of strrpos has changed from 7 to 8 php version cf
https://www.php.net/manual/en/function.strrpos.php

I don’t use “white list” option of wp-cassify but this should be buggy even with php 7.

I suggest to modify the line 1144 like this

if ( strlen($white_url)>0 && strrpos( $url, $white_url, strlen( site_url() ) ) !== false ) {

Thnak you for this great plugin !
