If you have this rpoblem using only default vB (no modifications active), then follow these instructions:

To troubleshoot this, please remove any hacks and disable your plugins, then see if you still have this problem.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

If so, reupload all the original vB non-image files (except install.php). Make sure you upload these in ASCII format and overwrite the ones on the server. Make sure that you rename the adminco directory in the vB software package to the name you are using before uploading.

If this does not solve your problem, then please post the problem on vB.com.
