some of those are plugins I wrote myself, if they look unfamiliar

Custom theme
Plugin version 0.3

The contents of the ?googfc error:

401. That's an error. The requested URL was not found on this server. That's all we know.
     The "slot size" shows the height as zero though.

Other details:

Our ad folks said the reason the ads are no longer displaying is that the sizes are now being sent incorrectly:

The issue why you are getting a 400 error here is that the request is sending incorrect ad size. In this example, it was sending these ad sizes :

• 1115x0 for the leaderboard_top
• 362x0 for the bigbox
• 1115x0 for the leaderboard_bottom

This may be related to #91 and #90.

Next steps:

• compare with No google ad manager ads appearing anywhere on website #90 to see if the ad unit sizes are off
• check to see if the variable renaming in 0.3 resulted in jquery.dfp.js attempting to get the height from an array key or object property that doesn't match the key/property that is actually in the thing.

• Does window.dfw have a value at the time the ads are loaded? May need to put that localization into the header instead of the footer. https://secure.helpscout.net/conversation/765188412/3113/?folderId=1219602

• is window.dfw correctly defined? From [this Helpscout ticket](https://secure.helpscout.net/conversation/765188412/3113/?folderId=1219602:

But after updating the plugin, the site stopped showing ads and there were below errors in the console:

-> GET https://securepubads.g.doubleclick.net/gampad/ads?gdfp_req=1& .... with 400 error.
-> Access to XMLHttpRequest at 'https://securepubads.g.doubleclick.net/gampad/ads?gdfp_req=1&pvsid=417413281066130& ........' from origin 'https://example.org' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

After digging up in the code, I found below DOM code in the footer of the website:

plugin ver 0.3 code:

jQuery('.dfw-unit:not(.dfw-lazy-load)').dfp( window.dfw );

which is different than the earlier version of the plugin which is as below:

plugin ver 0.2.1 code:

jQuery('.dfw-unit:not(.dfw-lazy-load)').dfp({
    dfpID: '<?php echo $this->networkCode(); ?>',
    collapseEmptyDivs: false,
    setTargeting: <?php echo json_encode($this->targeting()); ?>,
    sizeMapping: <?php echo json_encode($mappings); ?>
});

The older plugin was using these php values instead of the JS var dfw.

So, I commented out the below line in "/plugins/doubleclick-for-wp/inc/class-doubleclick.php" :

jQuery('.dfw-unit:not(.dfw-lazy-load)').dfp( window.dfw );

and added this code:

jQuery('.dfw-unit:not(.dfw-lazy-load)').dfp({
    dfpID: '<?php echo $this->network_code(); ?>',
    collapseEmptyDivs: false,
    setTargeting: <?php echo json_encode($this->targeting()); ?>,
    sizeMapping: <?php echo json_encode($mappings); ?>
});

which fixed the issue and I can see the ads on my site now and the category targeting also seem to be working.

• is everything that should be drawing from window.dfw.dfpID drawing from dfpID and not something else?

[benlk]

Aha.

doubleclick-for-wp/inc/class-doubleclick.php

Lines 159 to 163 in f73e00d

	$data = array(
	'dfpID' => $this->network_code(),
	'network_code' => $this->network_code(),
	'mappings' => $mappings,
	'targeting' => $this->targeting(),

window.dfw uses targeting and mappings; the added code uses setTargeting and sizeMapping.

• Add those terms.

That might reduce the amount of code needed on

doubleclick-for-wp/js/jquery.dfw.js

Lines 35 to 39 in bf4fcb5

	dfp_options = Object.assign( dfw, {
	"collapseEmptyDivs": false,
	"sizeMapping": dfw.mappings,
	"setTargeting": dfw.targeting
	});
