Errors with Ad Inserter when upgrading to PHP8

[ad_1]

My site is currently on PHP 7.3 – when trying to upgrade it to PHP 8, my hosting provider’s compatibility check tool reported some errors in two files. I am on Ad Inserter 2.7.18 and WordPress 6.0.2 as of time of posting.

/wp-content/plugins/ad-inserter/includes/google-api-8/vendor/phpseclib/phpseclib/phpseclib/Crypt/Common/SymmetricKey.php
contains errors relating to an “mcrypt” extension that’s deprecated.

/wp-content/plugins/ad-inserter/includes/phpQuery_8.php
has the error “”$this” can no longer be used in a plain function or method since PHP 7.1″.

Can I safely ignore these errors, or is something wrong here?
