Hey Andre,

I am sorry for the delay of this reply,

It seems like you are using 3.8 version, because this is older Easyblog responsive standard.

We already changed this default behaviour in Easyblog 5 to show social share buttons when you view on mobile.

To fix this, you have to apply this css fix into your current template css file. (After applied following code into your file, you have to clear all of your browser and Joomla cache before you view your site, so that it will load the new css on the page.)

#eblog-wrapper.w320 #ezblog-body .map-images, #eblog-wrapper.w600 #socialbutton, #eblog-wrapper.w600 #socialbutton .socialbutton-vertical {

    display: inline-block !important;

}
