With almost all website-providers, the permissions and the owner for the folders and scripts are set correctly when you upload the complete pws folder.
But in your case: https://www.loweprofile.com/pws2/nws-alerts-142/NWS-alerts_read_me.html => not allowed to display either!
That is an html file. So this is a permission error.
- check the date of the files in that folder. Are they newly created? Or still the ones from the download? The scripts need execution permission.
- change the permissions of that readme file and see what permission works.
- check the permissions of the pws2/nws-alerts-142/ with your ftp program and set the permissions for the folder AND the contents to 755.
Success,
