solved – plugin limit logins was the problem.
When the user tries to log in via /wp-admin it works! But just not on the login form from the plugin…
it is widespread and it happens on every login form. (user + passwort combination cannot be found).
I tried to deactivate my caching plugin but it didnt work either.
In the FAQ: “it’s likely that your server has database or object caching enabled. Disabling these caches should resolve the issue.”
How can I do that?
hmm I bought the plugin but I dont see the export option ..
