Cant upload new feeds

Hey guys,

Love this plugin, planning to upgrade to pro very shortly but in the mean time it wont let me add any new feeds, i just get the message saying this https://gyazo.com/bcc36cc5cfb08fc5a3d0e95b20ed3c51

I’m not familiar with ftp to turn on debug mode, but i could give you the admin passwrds to have a look?

Many Thanks

Jack
