Why are the text-align buttons not appearing in my CK Editor in Drupal 7?

Question

Essentially, I've been back and forth through settings and configuration for using the CK Editor as well as re-installing it but for whatever reason the text-align buttons for this WYSIWYG editor are not showing up despite the fact they appear to be configured to do so.

I'm using Drupal 7.19 and CK Editor 7.x-1.12. For clarification, this is the CK Editor as stand-alone project, not a part of the WYSIWYG project.

Also to be clear, this is not a problem of the buttons not working or text-align properties being stripped out, the buttons are simply not there. Which is a problem for ease of use for my end-users.

Why would this be happening?

Most likely you have downloaded a standard package which does not include justify plugin. Download the full package or add this plugin using online builder.

Thank you, I knew I must be missing something inane. – Brunabrunch

Answer 2

This is due to the "Limit allowed HTML tags and correct faulty HTML" filter settings. As outlined in this issue, you must explicitly allow those classes on the p tag https://www.drupal.org/node/2649546

<p class="text-align-left text-align-center text-align-right text-align-justify">

Also this is for Drupal 8
