I am running on the latest version of CiviCRM, 5.17, and when I go into CiviMail to create an email message the HTML wysiwyg editor does not load. I get a console error saying
CRM.wysiwyg._create is not a function
If I put a debugger right before the line I can see the the CRM.wysiwyg object does not have ._create method but it does have a .create() method. If I change the code to use the .create() method then it seems to loop for ever and the tab stops responding.
I had this issue on the previous version of civicrm, 5.13, which is why I tried the upgrade to 5.17.
There is a message during upgrade about updating the templates but when I click the link for more info it take me to a page saying the documents have moved.
I do have the ckEditor enabled on the site.
I am running on wordpress 5.0.4.
I did reset the cache and clear the templates_c folder but neither cured it.
Any suggestions would be appreciated.
