mojoPortal Hosting & Design @ i7MEDIA!
This often happens when there is a long period of delay between the submission of a form and the page load. It could also be caused by lack of memory for the application. What version of Windows is mojoPortal running on?
Thank you for a response any help is greatly appreciated.
I consistently and very quickly (31ms) get the exception any time I click "Sign In" button on /Secure/Login.aspx?returnurl=%2f. I have tried this on two different servers now, both running:
We have several mojoPortal servers running that same configuration and haven't run into this problem. I've added you to our Complimentary Support group, so you now have access to the form on this page: https://www.mojoportal.com/complimentary-support
If you're up for it, use that form to send us the necessary info to log in to your server so we can try to find the issue.
Found a workaround for this issue, looks like my problem is not with viewstate but with session, when I try to access the portal website from a different system i.e. not the one I am running the IIS on, I am able to login. I suspect it is not happy with the cookie domain. Thank you for your help. I will upload the logs to the support portal.
