Often when i select 'Run the Tests' there is no response

Tell us what’s happening:

Often when i select ‘Run the Tests’ there is no response.

Basically the console is not submitting, and nothing happens. It usually happens after i make a change to the original code.

Is there somethign wrong with the servers or website?

I refresh the page a lot.

I am on the Javascript first module of the second certificate.

Hi @Dan-Richards will you post your entire code and format it as a code block? Use backticks (`) like so below.

copy and paste your code here.

I have the same issue if I use Internet Explorer. I switched to firefox and Chrome and it works there.

Usually any syntax error will prevent you from running tests. In any other cases, I’d say it’s probably a bug.
Check the devtool for what happens when you submit.
