    14

    1713== Installation ==

    23 
    24 IMPORTANT!!!!
    25 PLEASE MAKE SURE THAT YOUR THEME HAS THE FOLLOWING LINE IN ITS HEADER FILE:
    26 `<?php wp_print_scripts(); ?>`
    27 
    28 ...Most high quality themes should have this already but if you're writing your own theme or using a custom theme that doesn't include this line, please make sure you include it in header.php, somewhere between `<head>` and `</head>`

    3221= How can I make the 'like this' link look prettier? =
    3322
    34 With CSS :) Here is the code that I use:
    35 `a.done {
    36 background:url("http://yoururl.com/wordpress/plugins/roses-like-this/action_check.png") bottom right no-repeat;
    37 padding-right:18px;
    38 color:#8bcb46;
    39 }`
    40 
    41 = The javascript is not working! =
    42 
    43 IMPORTANT!!!!
    44 PLEASE MAKE SURE THAT YOUR THEME HAS THE FOLLOWING LINE IN ITS HEADER FILE:
    45 `<?php wp_print_scripts(); ?>`
    46 
    47 = The javascript is STILL not working!!! =
    48 Do you call get_header() in your theme?  This is also needed, although almost certainly there anyway.
    49 
    50 = The javascript is STILL not working AGAIN!!! =
    51 The plugin expects to find the javascript file in a folder called `roses-like-this` under /plugins.  So if you have named the folder something else, you're probably getting a 404 error!
    52 
    53 To fix, you can either rename your folder `roses-like-this`  OR you can edit the `likethis.php` file and edit line `112` roses-like-this/ to yourfoldername/
     23You can use CSS.
     24- LikeThis links have the class `likeThis`
     25- Links that have been liked also have the class `done` (`.likeThis.done`)
