Let me start by saying I am new to DNN and was task to upgrade one of our old DNN site to the new verion. I've installed DNN on my local computer and had it running very quickly.
"Suddenly" I'm getting an error page with just Application Error. I've looked at the Exception table in the database but the information was not very helpful.
I'm hoping someone can point me to where I can get more details on the issue. If this isn't the right place for my message please let me know.
Thanks
Try checking the Windows Event Viewer logs for Windows Logs > Application, and in /portals/_default/logs/todays-date
At the time that was the only info I had, I did go look at the logs under /protals/_default/logs. After looking at the looks and doing a quick search in the community I found a post with a similar issue and she said she fixed it by deleting the temp folder. I have no idea what Temp folder she was refering to as I was not able to find any temp folder under the DNN site. Here is my log (edited for just the most recent event):

Posted By Sebastian Leupold on 17 Feb 2022 04:17 AM did you make sure, the ddrmenu file mentioned does exist and the ASPNET process has permission to access it?
As the DDR menu is listed as "not in use" in the Module Extensions some users uninstall it. But one should not do that as it's used in the Skin too. (but not as a module)
Thanks for the replies.
DDRMenu does exists and the specific file Menu.ascx also exists.
The ASPNet process does have access to the site folders.
This started happening when I rebooted my PC.
I will continue researching the issue.
Again, thanks for the replies and help.
