Hello scinetde,

Thank you for getting in touch with us. My name is Attila and I'm happy to assist you today. I appreciate your patience while we've been working towards your ticket.

Problems with the activating method such as this, are usually related to server configuration issues unfortunately.

Please check the LayerSlider System Status, located in the Options menu on the WordPress sidebar, for any error messages or notifications that could provide additional information on this case.

Thank you for the feedback. I've tried to login with the credentials you provided to look into this further, but they do not seem to work: Das Passwort, das du für den Benutzernamen support eingegeben hast, ist nicht korrekt.
Could you please check on them again ?

Thank you. My colleagues and I will look into this to see if we can find anything, and get back to you shortly.

We've managed to locate the problem. You are using an outdated version of PHP and that is causing the issue. LayerSlider requires at least 5.3.0. or newer to function properly.

Please contact your host and request an update, or if they provide you with an admin dashboard you could also do it yourself.

Thank you for the feedback, glad you could solve the problem. If you need further assistance please let us know.
