errors

I’m getting a few errors (I’ve removed the full path for clarity).

The first is on initialisation of the popup after clicking on thumbnails from the media library:
Notice: Use of undefined constant size_information – assumed ‘size_information’ in (…)\wp-content\plugins\post-thumbnail-editor\php\functions.php on line 255

The second occurs in the ajax callback after doing a crop and clicking ‘create thumbnails’:
Notice: Undefined offset: 1 in (…)\wp-content\plugins\post-thumbnail-editor\php\log.php on line 83

Notice: Undefined index: log in (…)\wp-content\plugins\post-thumbnail-editor\php\functions.php on line 57

Translation of that last part is: ‘wp_load_image is no longer in use since version 3.5! Use wp_get_image_editor() instead’
