I have 2 MT blogs. The first blog works perfectly.
But when I try to Manage Assets on the second blog or in the system overview, I get an Internal Server error. When I was creating this blog, I uploaded some images via an FTP program and not through the MT control panel (not for any particular reason, just force of habit). So I have images that are referenced in both Templates and Pages that were not uploaded through the Asset Manager. Would this be causing the problem? Is there any way to reset this info and start fresh???
Thanks in advance!!

Internal Server Errors are notoriously useless. Check the error log and see if it tells you something more.
Otherwise, just from what you have told me, I suspect ImageMagick. When there are problems rendering thumbnails or images, or any page that has them - ImageMagick can often be blamed.
Thanks Byrne,
If your assumption is correct, could this problem theoretically be solved by installing and using NetPBM instead of ImageMagick?
If so, can you point me to the EASIEST instructions to do this? What I've seen so far is a bit daunting.
Problem Solved:
I added the line:
ImageDriver GD
to the mt-config file, specifying GD as the Image Driver, rather than ImageMagick or NetPBM. So clearly the problem was w/ ImageMagick. Rather than try to figure it out, I just used GD to render the images. It was already installed on my host.
Thanks.
I am so glad that helped you, and so glad to have found an answer!
