I just upgraded to RC3, and after the upgrade thumbnails are no longer showing in the MODx Browser (see attachment). The site I upgraded is hosted at Mediatemple, but when I upgraded the local version of that site, thumbnails were shown in the MODx Browser.
I have noticed that the MODx Browser is using the phpthumb library to display thumbs, and in the console in Safari 5 I get one warning for every thumb that it is interpreted as an image but transferred as text/html.
Anyone have a clue what could be wrong on the remote server?
I have confirmed that the GD library is enabled.
Thanks
That fixed it.
