Logged into Website But Can;t Navigate to Other Pages

i usually use something like this after btnSubmit.Click

    Do While objIE.Busy: DoEvents: Loop
    Do Until objIE.ReadyState = READYSTATE_COMPLETE: DoEvents: Loop
   
    'now that we’re in, go to the page we want
    objIE.Navigate "http://severe-frost-552.heroku.com/"
    Do While objIE.Busy: DoEvents: Loop
    Do Until objIE.ReadyState = READYSTATE_COMPLETE: DoEvents: Loop

this code basically waits until the page is fully loaded after submitting your username etc to allow the page to log you in.
Then it redirects the IE to your next page
then it waits until it is fully loaded.

Check your website address, i couldnt even access it.
