Hello! I am having the same issue. Trying to update a button on a page with a missing internal link and get the same error. I’ve done everything I found on the web in order to solve the err_empty_response to no avail. My site is in GoDaddy but I am not the webmaster. Has anyone been able to get some kind of response from GD or found some sort of solution?
Having exactly the same issue since this morning. Has anyone found a solution? I am also on GoDaddy…
