I have a problem accessing the Navigation settings, and the left navigation bar no longer exists. When it happened, I was organizing this navigation bar and adding a new sub-site template. I also deleted a sub-site, but the top bar is functional and I can still access these Parameters.
When I try to Access to the Navigation Settings, a error page opens "an error occurered..."
"Das hat leider nicht geklappt. Es ist ein unerwarteter Fehler aufgetreten. Technische Details
Führen Sie die Problembehandlung mit Microsoft SharePoint Foundation aus. Korrelations-ID: f372659e-6290-e083-6033-ff532bfcde0c"
Please be very precise in your answer, I am working with SharePoint in german, but I am French... Sometimes complicated to find my in the Settings.
I have the owner permission. I don't have Access to SharePoint designer, the command line...
I'd like to know how to solve this Problem
Thank you in advance for your help.
