Error in default CS CART SEO addon

General

Hi,

I have some strange problems for a few days now, in my error log.
I can see some problems related to few addons, one is from AB, and I disabled that for now, just in case, another one is from MakeShop, contacted them already to check, and the third one is from CS CART, default SEO addon, the error is at line 2002, if someone can check and let me know how to solve that, and what is causing that problem. I can’t remember making some changes that can affect that addon…

Links for logs are here:

Thanks in advance!

The error:

Identifier "ajax" is not defined.

was fixed in 4.18.1. Please upgrade your installation to this version, in order to fix this error.

The error:

PHP message: PHP Notice:  Undefined index: option in app/addons/seo/func.php on line 2002

is related to a third party SEO object whose schema is defined incorrectly, with a missing option element.

I also recommend that you remove error_logs, which contain sensitive data, from public access.
