Hi Peter

Unfortunately we are unable to replicate this issue. May I ask what version of Chrome you are using? Have you tried updating Chrome to the latest version?

Hello Ciaran,

it seems the problem has to do with the height of the screen.
In the link you will find 4 pictures. The fist appr. 1000 px high has no problem. Then every picture gets a bit bigger, and the menu slowly disappears.
I am using Google Chrome Versie 52.0.2743.82 m
In Firefox there seems to be no problem.
I hope you have any ideay how to solve this.

Regards, Peter

Hi Peter

On what screen resolution are you experiencing the issue? May I suggest sending temporary administration access to your Joomla installation to info@joomla51.com and we will examine this issue further. For our reference please paste a link to this post in your email.

Thank you Peter

Sorry to say we are unable to access your administration with the details provided...

Warning

Username and password do not match or you do not have an account yet. 

Regardless could I ask you to try adding the following to the Custom CSS field of your templates parameters...

#container_header {

    min-height: 100vh;

} 

Strangely we are unable to replicate this issue at the same resolution.
