I have civicrm 4.7.27 installed on Wordpress 4.9.1 Everything was fine yesterday when I created new contribution pages. Then this morning I noticed that the Introductory and Footer message textareas of the Title and Settings tab of the Contribution pages are not loading the WYSIWYG Editor. As far as I can tell, this is only happening in this area, and not any other area that relies on ckeditor/WYSIWYG, but I am concerned that because this came out of nowhere, that it will show up in other parts of the install. Does anyone know what is going on? Is it possibly a known bug with 4.7.27? See screen shot for error messages.
Solved. The problem was caused by the new theme we installed. The theme Super Mag is not compatible with Civi and will break of the wysiwyg functions. Once uninstalled it worked properly again.
