1.5.3 Update Issues

OK, thanks. Narrowing things down…

Something else to try. In that same file, at the top of the prepare_response method, please add this condition:

if ( isset( $_GET['verify_prepare_response_called'] ) ) {
	return 'Prepare response was called! ##BEGIN##' . $response . '##END##';
}

So it would look like this:

...
	public static function prepare_response( $response, $args = [] ) {
		if ( isset( $_GET['verify_prepare_response_called'] ) ) {
			return 'Prepare response was called! ##BEGIN##' . $response . '##END##';
		}
...

We’ll be able to confirm that it is being called by requesting the page with ?verify_prepare_response_called=1.

added the code

OK, so that is not getting called even though ob_start() was indeed called with it as the output buffer callback.

Only thing I can think of is somehow you have a plugin that is cancelling the output buffer. But I would have expected “Prepare response was called!” to appear in the page because ob_start() did return true. Nevertheless, something else to try would be to add an argument to ob_start() to prevent it from being stopped.

So in the start_output_buffering method, replace this line:

if ( ! ob_start( [ __CLASS__, 'finish_output_buffering' ] ) ) {

with

if ( ! ob_start( [ __CLASS__, 'finish_output_buffering' ], null, 0 ) ) {

The 0 will make the output buffer non-cleanable, non-flushable, and non-removable.

Very interesting. Now the question is which plugin on your site is causing that to happen. Are you able to deactivate plugins one-by-one to see which one causes that issue to stop happening when that ob_start() change is not applied?

Turned out to be a custom plugin that was made for us, and shouldn’t have been running on that page. It has been fixed. Thank you very much for the help!

Is it possible to have the url and the info post deleted by chance?

Thanks again!

Can you share what the custom plugin was doing? If yours was doing it then others may be doing it as well, and if we can account for it we can improve compatibility.

As for deleting site health info, I’m not sure. You may be able to edit your topics to remove content. Otherwise, it would have to be a request to the support forum moderators as it’s not something I have the ability to do.
