Hmm, I don’t understand what an object comes to Ressio_Plugin_Lazyload class (and how it is possible at all). May I ask you to edit wp-content/plugins/psn-pagespeed-ninja/ress/classes/plugin/lazyload/lazyload.php file in the following manner: found a line
$params = $this->loadConfig(dirname(__FILE__) . '/config.json', $params);
and insert following code after that line:
file_put_contents(__FILE__.'.log', var_export($params,true));
? It will save lazyload input settings to lazyload.php.log file in the same directory. Could you post there the content of this file?
stdClass::__set_state(array(
‘image’ => true,
‘video’ => false,
‘iframe’ => true,
‘srcset’ => true,
‘addsrcset’ => true,
‘srcsetwidth’ =>
stdClass::__set_state(array(
)),
‘noscriptpos’ => ‘after’,
‘debug’ => false,
‘lqip’ => false,
‘edgey’ => 0,
‘skipimages’ => 1,
‘skipiframes’ => 0,
‘addons’ =>
array (
),
))
config.json in case it needed
{
“image”: true,
“video”: false,
“iframe”: false,
“srcset”: true,
“addsrcset”: false,
“srcsetwidth”: [320, 360, 640, 720, 768, 800, 1024, 1080, 1280],
“noscriptpos”: “after”,
“debug”: false,
“lqip”: false,
“edgey”: 0,
“skipimages”: 0,
“skipiframes”: 0,
“addons”: []
}
OK, the temporary patch is to found line #486 in wp-content/plugins/psn-pagespeed-ninja/public/class-pagespeedninja-public.php
$ress_options['plugins']['Ressio_Plugin_WpLazyload']['srcsetwidth'] = array_keys($widths);
and wrap it into the following if condition:
if (count($widths)) {
$ress_options['plugins']['Ressio_Plugin_WpLazyload']['srcsetwidth'] = array_keys($widths);
}
Thx, it does help. Awesome plugin, Denis!
May I ask you to add one feature for next release. There is no option to purge cache for single page. For example: I have some thousand pages with shortcode in them. Shotrcode generates html from database. I update database every day by cron and it can affect about 2-3% of pages. I can easily detect this pages and purge cache for them to see new data online immediately but plugin doesn’t support this option. I did my own solution but it’s not so right as it must be and it will not handle urls with GET parameters in it.
PagespeedNinja_Cache::__construct
#added
if ($_SERVER[‘QUERY_STRING’] == ‘ninja’) {
$_SERVER[‘REQUEST_URI’] = str_replace(‘?ninja’, ”, $_SERVER[‘REQUEST_URI’]);
}
#before
$uri = $_SERVER[‘REQUEST_URI’];
if ($uri === ‘/index.php’) {
$uri = ‘/’;
}
and
#added
if (isset($_GET[‘ninja’]) && file_exists($this->cache_file)) {
@unlink($this->cache_file);
}
#before
$cache = $this->readData();
now I can purge page cache just loading page with ?ninja parameter in it via curl;
also one important thing is PAGESPEEDNINJA_CACHE_DEVICEDEPENDENT is FALSE!
