So far I have tried the following without any success:
(a) Restart a new blog roll;
(b) Log in to the blog using different browsers, especially Chrome; and
(c) Ensure all browsers are updated.
If any of you have experienced and resolved this Blogger bug, I would appreciate it if your solution could be posted in the comments below. If all else fails, I can only hope this bug will resolve itself over time as have most bugs I encountered when using Blogger. Google bot/god are you listening?
