I am seeing an new error in the Live Preview section of the Template Designer.The following errors were found:
isExperimental: Required field must not be blank
Upon examination of the URL window in the browser, the source of the problem is seen.
It appears that we are seeing one more reason why routine use of Draft Blogger is not a good idea.
People who are seeing the "isExperimental" error have only one choice - stop using Draft Blogger for template customisation.
Many of the blog owners reporting this problem have previously selected the option to use Draft Blogger, by default. When this is the case, returning to standard (non Draft) Blogger is not complicated.
- From the dashboard home page, next to the blog list, find the gear icon.
- Click on the gear, then on "Edit User Settings".
- On "Edit User Settings", and under "General", de select the option to "Use Blogger Draft".
- Log out of Blogger, clear cache, cookies, and sessions, restart the browser, and log back in again.
Having reset the redirect option (if necessary), always login using "www.blogger.com", instead of "draft.blogger.com".
