Failed to load resource: net::ERR_FILE_NOT_FOUND

[Benjamin_Zekavica]

On much WordPress Installtions I get a error message in Browser Console Log:
Failed to load resource: net::ERR_FILE_NOT_FOUND

[subrataemfluence]

It is clear from the error message that the file in question could not be found in referenced path. This I don't think a core WordPress issue. I tried to reproduce on a clean WordPress install with no addition plugin activated. I used WordPress bundled theme twentyseventeen.

Can you please double check what file is giving this error. The filename is listed at the right of the error message in gray color. To my understanding it is related to some theme / plugin being active in the system.

Please reopen this ticket if you can reproduce the bug with the following configuration:

• A clean WordPress install
• No additional plugin except bundled ones is installed activated.
• No additional theme is installed and activated except the bundled ones.

Thank you.

Hi @Benjamin_Zekavica, welcome to WordPress Trac! Thanks for the report.

I don't see the issue on that page, the HTML source doesn't have that URL either. Which browser are you using? Does it still happen with all browser extensions disabled, or in another browser?

Google search for 70b682e3-6d0d-4d35-8043-29017af10fd9 only shows this ticket.
