Hello everyone,

I am trying to perform an upgrade to 4.8.4 on a client's site. 

The first time I attempted the upgrade it started ok and then fell over.

Now everytime I try a subsequent upgrade, nothing happens.  The browser just spins in an infinite loop.  I'm receiving no errors which is making it very difficult to debug.

I have followed the upgrade instructions very closely.  My web.config is correct as far as I can tell.

Any help would be appreciated.

Tom.

Thanks Sebastian,

It's version 4.3.5.  There is a 3rd party module that is dependent on version 4.8.4, otherwise I would upgrade to 4.9.0.

Thanks for the tip about the web.config file.  I will see if it helps.

Tom.
