Thank you for your response.
I am a sole developer and have used SmarterTools for free for several years. For that I thank your companies generosity. The upgrade I made was to take advantage of the Community portal. I was very reluctant to do this upgrade as my previous experience with upgrading SmarterTrack has been dismal.
It has taken me 3 goes at upgrading 7 to 14 and since your response I have performed the actions again without success. After realizing that the new App_Data folders contents also required installation on top of my current installation and then playing around with web.config in the root directory I have everything working except that I and any users cannot login via the Portal.
As Administrator, I can directly login to the Portal without problem.
I really don't think it appropriate for me to have to pay $50 (about AUD$ 75.00) to find out what's wrong with my installation as the issue has been created by a change somewhere in versions 8,9,10,11,12,13 and now 14 that affects the login function.
I did ask here hoping that there would be someone with enough experience to recommend a course of action or requirement that I have not yet undertaken. A search of your KB and the internet has proven fruitless.
I will now add to the 2 days it's taken me so far to try and read all the release notes.
If in the meantime, you or someone can come up with some suggestions or ideas, I would greatly appreciate it.
