The mail just won't send.

The SMTP username and password is correct. I have tested with two SMTP credentials, one that is working on a wordpress site on the same server.

PHP version is 8.3. Drupal version is 10.6.1.

I get similar error with module 'SMTP Authentication Support'.

Here is the error message on verify page when I send a test email:

Failed to authenticate on SMTP server with username "smtpusername" using the following authenticators: "PLAIN". Authenticator "PLAIN" returned "Expected response code "235" but got code "535", with message "535 Authentication credentials invalid".".

Is there a simple way for mail notifications to work with Drupal 10?

When I select a term in Views search form it shows the term ID next to the selected term e.g. Apple (13).

How do I stop it from displaying the term ID next to the term?

Also wondering what is the practical use of this feature when it is meaningless and confusing for the end user?

I am trying to create an ECA workflow to assign a custom role on user registration based on drop down field selection.

User selects Value 1 from Custom_Field on registration form, clicks Register, Custom_Role gets assigned.

Can someone point me to what the ECA workflow should look like, either Classic or BPMN version?

ChatGPT has provided dozens of suggestions, none have worked.

I could have built this with Rules module without any help but ECA has completely lost me.

Drupal version is 10.6.1. The site gives this WSOD:

The website encountered an unexpected error. Try again later.

It was a test site with about a month of work done. No backups, never thought this could be a problem with Drupal in 2026.

Un-installed rules module with composer but error remains.

Is there any chance of recovery?
