Hello there, I cannot seem to figure out how to allow my users (who have FTP access to their servers) upload .jar files. They can upload all the other files, create directories and what not, but when they try to upload a .jar, they get ''Critical File Transfer' which is a permissions error. Is this internal and specific to TCAdmin, or does it come from a problem with my FTP server? I'd suggest it to be TCadmin considering these people are able to log into their server directories and change things (everything but .jars) Regards, Jack.
