Your CMS website will accept a number of file types, but in order to have the most success uploading your files, please review the extension types and file names the CMS will accept.
File names must use only letters, numbers, hyphens, or underscores. Symbols and spaces are not allowed. You may rename your file on the computer before uploading, or rename the file upon upload in order to fix this problem.
If you feel your file meets these guidelines but continue to experience problems, please submit a support ticket.
