My best guess is one of two following…
One, the document root can not be determined automatically. So you have to manually set the DOCUMENT_ROOT here’s how:
Add the following to the timthumb-config.php file found here:
This is what you need to add, make sure to change the doc root accordingly:
/my/doc/root will be will depend entirely on the server setup. If you go to the the Connections : Dashboard admin page and look at the the System widget; there will be a constant named CN_PATH. The doc root should be the beginning portion of that path. What I can tell you is that from the
wp-content on will NOT be part of the doc root.
Two, some server setting is preventing the script from reading the images and if that is the case, so, I do not know what that could be. Maybe a rule in the
.htaccess file or something your webhost has configured. If you have any security related plugins installed, perhaps they’re blocking content.
I hope that helps point you in the right direction.
