Thank you, this hint was very helpfull. Now it is working fine.
Hi Angus
Thank you for your answers. There was WP Super Cache installed, which I have disactivated now. I disactivated also another plugin which could possibly block material design: Meta Generator and Version Info Remover.
The code is identical with what you published on your demos-page. It will be easy to adapt thes as soon as we have succeded to debug it.
Thanks, Schlorian
Thank you! Now it is working 🙂
Deactivating was not enough. I deleted the plugin and manually deleted the updraft-folder. After re-installation everything works fine.
Best regards
Schlorian
