Hey, I've been using Wordpress. Recently some of my thumbnails started disappearing and the newer images have not been loading at all. I've searched everywhere for a solution but unfortunately I've been unsuccessful.

When I try to view the thumbnail images that aren't loading, I get this error message.

Warning: touch() [function.touch]: Unable to create file ./cache/faf0cc6f8bbe3aa435179e50401e3236.jpg because File too large in /home/content/18/5710018/html/wp-content/themes/groovyvideo/thumb.php on line 149

Warning: Cannot modify header information - headers already sent by (output started at /home/content/18/5710018/html/wp-content/themes/groovyvideo/thumb.php:149) in /home/content/18/5710018/html/wp-content/themes/groovyvideo/thumb.php on line 159
My website is http://www.hipstrumentals.com btw. I can upload my thumb.php file if need be.

Please help. Thank you.
