Hi,

A 500 Internal Server Error in Odoo means the server failed while processing the request. It’s not a browser issue and it’s not a message you can fix from the UI alone.

The only way to identify the cause is to check the Odoo server logs. The log will show a traceback pointing to the exact problem — usually a Python error in a custom module, a broken view, a missing field, or a misconfiguration. Once that underlying error is fixed, the 500 error disappears automatically.

Hope it helps
