I have two sites on localWP. One is no longer responding. I have the error message ERR_INVALID_HTTP_RESPONSE. The other site is working, so it doesn’t seem to be due to the localWP configuration. I don’t know how to fix this bug.
Thanks in advance for your help
Can you try changing your Router Mode to Localhost and see if that works? Preferences>Advanced>Router Mode
Are you running other developer applications simultaneously? That could also cause similar issues. Apps like MAMP, XAMPP, or Docker for example.
Do you have any antivirus, security, or firewall applications that could be blocking Local?
