Fixed my problem. Went into my cpanel and deleted the ftp file.
It must have a conflict with some other Plugin I use for this site because I have installed this plugin successfully for other sites I have built. I suspect it might be the EWWW Image Optimizer…as I have had similar problems with that plugin on other sites I manage. But I have not confirmed that was the problem.
These are the plugins I have installed:
