Hey Moshu & Podz,
I tried deleting all of the /wp-admin/ files, then reuploading them. That didn’t seem to do the trick. Going with your thoughts that this was an FTP error, I dumped my install (MySql) and used a different FTP program to upload.
Same exact result. Wors fine under simple mode, same errors as originally posted when on Advanced Mode.
What would be the next best course of action?
Truly appreciate your time/help.
