Ads not delivering (PARSE blocked)

[cbitterfield]

I have setup a basic Revive Adserver setup. I am getting mixed and unreliable results. (It worked for a little while and then stopped).

This error message is in the javascript console:

A parser-blocking, cross site (i.e. different eTLD+1) script, http://www.[REDACTED].us/ads/www/delivery/spc.php?zones=4&source=&r=52034309&charset=UTF-8&loc=http%3A//, is invoked via document.write. The network request for this script MAY be blocked by the browser in this or a future page load due to poor network connectivity. If blocked in this page load, it will be confirmed in a subsequent console message. See https://www.chromestatus.com/feature/5718547946799104 for more details.

I am guessing it is based on CORS or an Apache setup issue. The question is what side?

The debug option on revive shows no data at all. 

What I am looking for is an example apache config for the "CLIENT" side website. I am guessing that's where the issue is.

 

I have tried:

# CORS
                Header always set Access-Control-Allow-Origin "*"
                Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"
                Header always set Access-Control-Max-Age "1000"
                Header always set Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept, client-security-token"

 

RewriteCond %{REQUEST_METHOD} OPTIONS
                        RewriteRule ^(.*)$ $1 [R=200,L]

 

I am not getting any error messages on either side Apache, or Revive (just no ads). The setup did work once. I have also tried "application/javascript" instead if "text/javascript"

Looks to me from the error message like it's a performance issue, not CORS. That's what the message says after all.

I switch to ASYNC javascript. (the machines are doing nothing else but testing). 

Now 1 out of 10 times, I get an ad. There are no errors in the debug log, error.log on either machine.

Works better on firefox, random results on Chrome or Safari. 

I didn't do anything and it started working again. I have tried changing PHP versions to 5.6, 7.0, 7.1
