What is it that causes a page to go back to a previous page when for instance you make a post and then the confirmation page shows which should then automatically refresh back to the page you were on before making the post - if that makes sense
And if it works on one browser but not another is it a coding issue or a browser setting? Both IE by the way but different machines

it is usually done with a redirect, it could be either code or browser Are both IE versions the same?

Both are IE 11 but the one that works is ion my desktop, the one that doesn't is on a Windows 2012 server - it's just that I'm testing the site prior to pressing the big green button and needed to know

could be settings in the server version are more tight perhaps but wouldn't have thought that would affect the return after a post. you could try using F12 and then check the network trace to see what is happening, it may also highlight any javascript issues that may be hiding but causing a problem

Yeap, setting in Internet Explorer - Tools>Internet Options >Security> Custom Level

then enable 'Allow META REFRESH'

Big green button pressed and DNS's changed - all going to plan so far [^]
