Dang! You were right. I double-checked EVERY file upload, EXCEPT that vb3 template directory. Somehow I skipped over checking that one. I had two bad ones there. Now it's working just perfectly.
I have so many problems with bad file transfers. I costs me so much damn time in debugging. I've tried two different ftp programs, Filezilla and CuteFTP. They BOTH mess up regularly--no matter what I do. Anyone have any suggestions for a fool-proof, error-free ftp program?
