Custom Fields not Visible After Plugin Deactivate

Hi Javier,

This is a great lightweight plugin for importing user data.

I discovered that custom fields imported by the plugin are no longer visible if the plugin is deactivated. Re-activating the plugin still does not show them. I was able to get them to display again by re-importing a single record, but this is not desirable as a mistake could change all of the fields.

Sometimes it is necessary to deactivate plugins to locate memory leaks or solve “white screen” issues. Is there any way to make make the custom fields added by the plugin permanent, or is there a better way to restore them if the plugin is deactivated? Thank you!
