Internal Service Error After Clearing Browser History and Cache


I am running my Nextcloud server on a Raspberry Pi. Everything was working fine until I decided to clear up my browser history and cache. I then receive an error message for my cloud server as follows:

"Internal Service Error

The server was unable to complete your request.
If this happens again, please send the technical details below to the server administrator.
More details can be found in the server log."

I am totally new to this and I am unsure how to go about this situation. Someone please assist me with this issue. Thanks.
