Some downloads not working

Hi, this plugin has worked flawlessly for me for a number of years. Yesterday I noticed that some of my downloads were not working (all of my downloads are pdf files). No error message shows, just the blank grey screen that normally precedes the downloaded file shows and stays there.

Refreshing doesn’t work, however if I copy and paste the link into another tab, it will sometimes load properly, other times the same grey screen shows.

I use Chrome. I tried clearing internet files etc but it hasn’t made a difference. When I use Firefox I have no problems- all files download as they should.

Some of the downloads on that page work, some don’t.

Any ideas? Thanks,
Scott
