Template freezes im sitefinity 6.1
This behavior is strange. We need to try and identify what is causing it. In order for us to do so, please specify what you are doing with your template. Is the template build on a master page or with Sitefinity's template editor? What placeHolders do you have on the template? Do you have any layout controls that execute certain logic behind them? Do you have any placeHolders in your <head> tag? What do you do in order to get the template to freeze?

Yes, template is build on Master Page. I am using the place holders for some sitefinity widgets and static html. I do not have any layout control you asked for. Yes, I have placeHolder in <head> tag for logo and login control. I just use that masterPage to create a template as directed on sitefinity forum, it runs fine on local machine but on live it dont allow me to edit as it gets frozen.
You seem to have answered your own question in this response. Default convention dictates that you can only have scripts, metadata and links to external files in your page's <head> tag. Placing ASP.Net controls such as Sitefinity widgets in the <head> will cause your page editor to break or freeze as you like to put it.
I do not know why this behavior is only present on your live environment only, but it should be constant every time you place a widget in the placeHolder located in the <head>. What you can do to fix this behavior is the following:
