After a DNN site on a "shared cloud hosting" jammed, I asked for the app pool to be recycled which probably fixed the problem.However all users who were using the site when it jammed have been left in a state where the browser in use can no longer login to DNN.This is very strange. In my case it is Firefox that is jammed. I have tried reinstalling it, but to no avail. Other machines on my network have no problems. Colleagues in different countries report the same thing.I can only presume that something has affected the Windows registry for the browsers affected.Any ideas? A number of my users are affected by this.Gad this editor is dire.ThanksJC

Everything has been cleared and browsers reinstalled, to no avail.I have written my own login module that works fine, but the original module has died on the machines affected.Very strange.JC

Solved this by adding a DNN login module then hiding it.
