Tried installing

I’m not sure if there is in fact an issue with running DM and EDD but when I saw this plugin decided I should use it. Once it was installed there was a PHP error and I don’t know how to fix. Unfortunately I didn’t capture the exact error. I know it was a missing _____ that the code expected to find. I deleted said plugin, but had to do it through the Cpanel.

So two queries

1) do I need it – where/how is there conflict?
2) If I ran the experiment again would you want to see the error?

Thanks
