I am running Odoo Community V13 on Ubuntu. I installed some third-party modules, but those have been installed for a few weeks. Now I suddenly can not access Odoo, and got the following error message:
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
The following is the log file:
