Activation URL not working

Hi there,

I’m encountering a problem with the activation link functionality in the plugin. When new users register for a membership, they receive an activation link via email. However, clicking the link redirects them to an incorrect URL that looks like this: https://url8564.domain.com.com/ls/click?upn=…

I’ve added no such URL prefix to my website or plugin settings. I’m unsure where this “url8564” is coming from. This incorrect redirection is preventing users from activating their accounts and logging in successfully.

Please let me know if anyone else has encountered this issue, or if there’s a known solution. Thank you for your help.
