Hello.

After update to 4.7.18 some users (not all) have problems validating account:

In Logs I have this error:

Array
(
    [error] => invalid_grant
    [error_description] => Missing code verifier.
)

The error provided does not look to be related. The error provided deals with OAuth, which does not require email validation.

If you're having an issue with email validation and you're using SendGrid or another email service which tracks link clicks, please disable this for further testing.

You likely have a customised email template for the validation emails. You'll need to revert this to the default and then re-apply your customisations.

Yes I have customised email template.

I have reverted it to see if it solves it.

Thanks.

I use Amazon SES and don't track links.

Sounds like that may be the root of the issue. Please let us know if it doesn't solve it.
