Upload all your newly modified files to the server via Dreamweaver as you would normally. Then use filezilla to check and change the modified file permissions manually. Right click (or ctrl + click for mac) over the file to be changed and click on the option File permissions…
Folders are meant to have the 755 permissions number and files should have the 644 permissions number. Dreamweaver changes the file’s 644 to the strange 621. 621 results in any viewer to your page being ‘forbidden’! Nice ey?
