Hi, Krikor. This is unusual but i have noticed my site eats up my data bundles alot when im accessing it through a mobile phone. I have about 10 images converted to PNG. could this be the reasons why it takes alot bandwidth to load?

Thanks

Not really they are not heavy.
Your biggest image is 250 kb which is not too much.

Try the following:
a) Turn on caching (progressive) and choose APC if available.
b) Try to minimize HTTP requests by disabling k2.css, custom.css and custom.js if you are not using them.
(K2 Parameters, and template params respectively)
c) Enable gzip compression (Global configuration)

I think these should be enough.
You can ask your host for some server side tweaking (varnish cache) or finally if you are having too much traffic you should use a CDN.

That seems to have worked. Thanks alot.

1. And the the Open Graph issue is back. I cant share articles on facebook. The links are broken.
2. There are social share icons under articles that shows squeezed now but they were working well days ago (Check the screenshot: imgur.com/GvILzLK)

For some reason the facebook scrapper cannot access your site.
It could be your custom htaccess file, or a security extension.

If you haven't installed a security extension then you should contact your hosting provider.

How does htaccess file affect Open Graph? I have not installed any security extension.

It can block access to scrappers, bots, spiders etc.
You need to ask your hosting provider if he alters the default htaccess files or has any "out of the ordinary" security settings.

PS. The debugger's result should be like this : developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fdemo.nuevvo.com%2Fcommercial%2Fj3x%2Fkiji%2Findex.php%3Foption%3Dcom_k2%26view%3Ditem%26id%3D68%3Ametus-purus-volutpat%26Itemid%3D147
