Good Tech Support

Hello, I have a problem with my site. It has an optin form in the sidebar, but sometimes for some strange reason the optin form appears at the bottom of the site, below the footer?! Other times it is in the sidebar again. Does anyone know how to fix this? Here is a screenshot https://www.evernote.com/l/Ag23dxMlq_lBBaV8cha9COkcf7GqZXWcq5k

Many thanks in advance.
