Welcome to the past! 👻
Unfortunately, FCKeditor is no longer maintained. RIP ❤️
Or, you can discover CKEditor 4, which is an enterprise-grade WYSIWYG editor with countless features and wide browser compatibility including the legacy ones.
This release fixes the encoding of the distributed files of version 2.4.1, which affected some PHP installations. It presents the same features of version 2.4.1, with no additions.
Upgrade from version 2.4.1 is necessary only in cases where strange characters appear at the top of pages containing the editor (which is actually a PHP bug).
