# Errors on uploads

 * Firstly its WP v2.9.2 (not offered in pulldown) and Gallery v1.5.3
 * Seems everything is working properly, yet I always get lots of errors when uploading
   images such as the following below.
    Seems the gallery works fine, and the theme…
   Any idea what the errors are and how to fix? The progress bar still works as 
   the errors are being displayed… (Just a partial list of errors below – links 
   modified with generic text for this forum post):

 * Looks like you have a problem with the shopperpress plugin.
