HI guys – have updated to php 7.0 which has worked. Plugin now appears sound!
Thanks for the update tip… it got me on the right track.
I have managed to update the php version from 5.1 to 5.6. Which means the previous version of wpdownloadmanager worked on php 5.1
I am still getting the same error with this new version.
This has not solved the problem. Any other ideas?
