Hi,
Easy Profile extends Joomla user management (not replace), so all Users plugin and Joomla custom fields will continue to work. You can try this with free version.

Of course Easy Profile (like Joomla) append Joomla custom fields and Users plugins at the end of the core fields.

Note: you can see and edit Joomla fields and fields from User Plugins with a normal way but Easy Profile does not manage these fields for Users lists or Search features.

Thanks for the quick reply and the information.
So Easyprofile works as I thought it would.
Weird thing is that if you open a specific user from the frontend userlists, the Joomla fields all show up, but their content is not displayed at all in most cases. Some fields show up correctly, but others do not. Same problem when you try to edit the ujser record. Joomla 3.7.5 Dutch.
So I guess the best solution for using easyprofile is to import the userdata into easyprofile fields, so I can use all extra features. As far as I know there is no other product that has all tour features, so I will create a test site using easyprfile fields instead of joomla fields.

Hi,
mmmh... you have right, seems that between 3.7.0 and 3.7.5 there is some changes in Joomla fields. tomorrow we will release a new version that fix this. thanks for report it

Thanks!
I am now taking a closer look at easyprofile professional and will keep you posted on my findings.
