I have installed Light Box Plus. (not sure that is the problem) I am trying to upload images and it hangs at 36% or 62% or whatever and then a red "IO error" message appears.
Additionally...not sure if this is related, but if I want to put up images separately on a page (the customer wants to do this) Extra code gets thrown in between the a href tag and the image tag, so it looks like this on the browser
Wordpress 3.0.1
Lightbox Plus 2.2
Atahualpa 3.4.9
