Header does not scale...

Last weekend I launched my blog www.getwetsoon.de

All in all good feedback but a few people wrote to me, that my header (with the logo) is not scaling (see added picture).

Can anyone tell, what the problem is?

Happy to hear from you.
Tom

sorry can’t help you (struggling with slides myself!).
However I’d like to know how you replaced the Read More by the german version.
Txs !

Hi Tom,

I hope you are well today and thanks for posting here.

I visited your site and the header image of your site is scaling well for me.

Could you please ask those people which browser they are using so that i can test it on that browser?

Kind Regards,
Movin
