Hi. My name is Darling. I downloaded an installed the plugin on my website I must say is a very nice easy to use plugin but I am having trouble with guess post ok. First when they come for first time they are able to upload a picture of their dog you can see it here http://breathtakingyorkies.com/ The problem is when they come the second time they get this message http://imgur.com/ercXfJu they contacted me saying they don't even remember opening an account with us. So how do I fix it? If I have to buy the pro version I will but really need to know due to the person that are using this website most of them are old and have no computer skills and most of them just using Facebook. I need to keep it simple for them. So please any help I will appreciate it.
I have tried to reproduce this issue but failed. It could be a has a chance of theme or plugin conflicts. You can disable all your plugins except User Frontend and switch to a default theme of WordPress like- Twenty Twelve, Twenty Thirteen, Twenty Fourteen and let me know the results.
