This plug-in is out-to-date but there are several plugin fixes.
Open up sponsors-coursel.php
1. First fix: add media button not appearing
On line 369 you will find the following code:
echo _media_button(__(‘Add an Image’), ‘images/media-button-image.gif?ver=20100531’, ‘image’,$scwp_plugin_name);
replace with:
echo media_buttons(__(‘Add an Image’), ‘images/media-button-image.gif?ver=20100531’, ‘image’,$scwp_plugin_name);
2. Second fix: common jquery issue (interfering with other jquery plugins within your installation)
On line 68 you will find the function sponsors_carousel_enqueue_scripts, within this function delete the following code:
// jquery
wp_deregister_script(‘jquery’);
wp_register_script(‘jquery’, ($plugin_url . ‘/jquery-1.4.2.min.js’), false, ‘1.4.2’);
wp_enqueue_script(‘jquery’);
