Cannot upload Rar files in Sewing magazines - New

I have just failed to upload a sewing magazine. The images uploaded OK but when I tried to upload Rar files the option is only for 10Mb jpgs not Rars. Can someone check please & re-instate the option for Rar files.

Many thanks  Nana

You need to use the Chrome browser to upload in this section.
When you click on "Browse" to find the attachment on your computer, you need to make sure you select All files in the drop down menu.
