I have a strange issue here after upgrading from XF1.2 to 1.45 where by I can not view the 'Display Node Tree' via AdminCP.
I just get an IE message stating 'The website cannot display the page'.
All other links appear good (that I have checked so far). File Health Check reports no problems.
Not sure what is going wrong
I am currently moving host and so am having to access the site via an ip address (temp url). Don't know if that is an issue or not.
PHP version 5.6 is running on the server.
