I can't Save HTML or text from blog Layout


Hello, Am a blogger and I was formerly using awesome theme template powered by blogger. I recently changed my blog template to a custom template and it was working fine at first. Suddenly, everything changed. I found out i have access to my blog layout but can’t save any HTML or Text i insert from blog layout. I have tried refreshing the page, and still each time I insert the text or HTML code into the content field, it refuses to save. I have searched Google forum for a reasonable solution and still came up with nothing. Kindly come to my aide.
