Ok so the "Lost your password? " option on the "my-account" page is redirecting to the main/root site and not the subsite.
I found this question previously asked here: https://premium.wpmudev.org/forums/topic/why-does-the-sub-site-forgot-password-button-redirect-the-user-to-main-site
I followed that guide on my site and added the code found on: https://gist.github.com/eteubert/293e07a49f56f300ddbb in the following ways to my site: 1: added to child functions.php(removed top <?php tag),2: i added the plugin as a "mu-plugin",3: Idownload the zip directly from the site and uploaded it as a plugin(which is currently still active), 4:i also added the code as a snippet via the plugin "snippets" but none of those did the trick for me.
Can it be that the solution is not currently working in 2018 or could I possibly be doing something wrong or is there maybe another solution to this error?
FYI i am using wordpress Version 4.9.8 and woocommerce Version 3.4.2( i know woocommerce also changes the my-account page)
