I have released the latest version of Add to All. This version brings one major improvement and a few minor changes. As usual, existing users can update the plugin from within the WordPress dashboard. New users can install this similar to any other plugin.
WordPress 4.9 introduced better code editing using CodeMirror. Add to All has multiple settings that allow you to add HTML into the header, footer and feeds. Add to All v1.6.0 incorporates CodeMirror which allows code highlighting, auto-complete and to some extent, error checking.
WordPress minimum version
Will the addition of CodeMirror, Add to All v1.6.0 requires at least WordPress v4.9 which was released on 15 November 2017. If you’re not running the latest version of WordPress, please consider upgrading to the latest version. If you do not like Gutenberg, you can always install Classic Editor plugin.
Move to WebberZone
I have also moved Add to All under the WebberZone umbrella. You can now find this on its dedicated page. I will also work on updating the documentation in the Knowledge Base. The method of getting support remains via the WordPress.org support forums.
