This is a beginner's question -- surely already answered but I don't know how to find it:
When a coding/system error message pops up during processing of a PHP script or possibly JavaScript, its title is usually "The page at localhost [or other URL] says:". Its content usually includes a load of non-rendered HTML code (<b>
, <br>
, etc), a long reference to a PHP manual, an actual error message, and a reference to where the error occurred. Because the HTML is being ignored, the whole dialog is hard to read.
How can I get such windows to appear styled properly, as surely intended by the "folks at PHP or JavaScript", or at least appear in simple text with line breaks?
Please note: It is not an error message that I am intending to pop up in response to any user action; I don't know what is causing the message. Also, I'm not seeking advice on how to make user-friendly software or on how to do continuous development-and-delivery
