I deleted WPDM 3, uploaded WPDM 4 zip file and the WordPress says it failed to load because plug in found.
I just download the Pro version and the files are not showing up in the package on the blog post ( 0 kb) when I have uploaded the file and the file manager shows that the file is attached.
Same issue on my blog. Titles and descriptions were working fine until a couple weeks ago. I don’t remember if there was an update or not.
