I have a problem whith wysiwyg editors, such as tinyMCE, after installation this module.
Editor are displayed only on one language body, for example, if i have two languages, i have two "body" fields, and only one of them is have tinyMCE editor.
What can i do to fix this, i want to use tinyMCE editor on all languages "body" fields.
