I used dw8 to build this page fusionoutside dot co dot uk look under the corporate hospitalty and gallery page you will notice that a password prompt pops up how do i remove that ? sometimes its there sometimes not ,if you refresh it appears again somebody said I should look out for HTTacces,Authty codes in my html but there is nothing of that sort.
I dont think it is html issue, I beleive something on the web server? Where are you hosting this? What web server? Windows or Linux?
Are you linking any images from password protected folders? Line 222 on corporate hospitality and line 283 on gallery may cause this error.
No that's the thing I dont have any .htaccess or auth type file in my page so its hosted with fasthosts in the uk I have heard very bad stories about them
