WP Touch doesn't always load the page

I use WP Touch to create a mobile theme for my site. I am only able to test it from my Samsung Galaxy S3, on chrome and dolphin browsers.

Recently I have noticed an intermittent problem. When certain pages are loaded, sometimes they load, and other times they simply don’t, and I get a “Web page not available” error.

If a page is not loading, refreshing it will make no difference. Restarting the phone helps sometimes but not always.

Is there anything I can do about this? And is there a WP Touch forum where I should post this directly?
