I'm getting the excat same error message after upgrading as well. However, the wierd thing about my error is that I do not get this error if i access the site on the server using http://localhost
:## (i wanted to upgrade sitefinity 3.6 to 3.7 on our development server first. So I have bounded the applciation to port ##). I only get this error if I try accessing the application using the ip address of the server, i.e., http://22.214.171.124
:##. Is there something I'm missing in the settings on IIS or in the upgrade steps? I applied the upgrade patch SP3 for sitefinity 7.
Few things to note:
1. I do not know what edition (not version) of sitefinity we have, i.e., i don't know if we have community or the standard or what have you edition. How do I check for this? Will this one effect what upgrade patch I apply?
2. I don't see any of the custom controls we had in the Add Controls
section after I upgrade it to version 7. Is there a step i'm missing?
3. Once I log in using the localhost, I do see that the sitefinity version is 3.7.
Any response is appriciated. Thanks in advance.
