• Dear developers!
    I recently installed W3 Total Cache and also tried hands on WP minify. Both pluggins give my website the shape of a garbage. Needless to say, the css and js are the real culprits ??

    Could any of you spare some minutes and have a look into the blog and give me any clue? I’ll be grateful to your help and support.
    Best,
    Alex

    No it wan’t working fine on localhost (he said so)
    we do not have localhost installed on our computer….He was right in one way that the website started opening very fast.

    He said that timthumb was putting the cpu under a lot of pressure and created too many queries and hence he removed.

    If it wasnt working fine – why did u guys went ahead in making that solution on live ??

    anyways

    do you know what size did you guys kept for the thumbnails ?

    in your functions file try this code out (again test it first on localhost)

    if ( function_exists( 'add_theme_support' ) ) {
    	add_theme_support( 'post-thumbnails' );
            set_post_thumbnail_size( 150, 150 );
    }

    where i have 150, 150 add your width and height

    He said this was the previous timthumb.php which he removed

    Could you please tell me where you are located? I live in Delhi and Mousumi is asleep….she literally cried today when the developer gave in.

    If you go to the front page of the website and scroll down, you will find Mousumi’s email id. If you come on Skype or google chat and help her out on any of your convenient time, we’ll be so grateful to you.

    PS: she will do as suggested..tomorrow we are going to create localhost n do the testing.
    Not sure if BlueHost can provide us the backup of the site in back date.

    Cool, i have dropped her an email with all the details
