display of plugin "Metaslider" non being responsive

Hi,

I am using since I first installed Fluxipress a plugin called “metaslider” which is theoretically responsive, at least it was once (with Fluxipress theme).

I am currently using wordpress release 3.78 yet (not updating to 3.8. until plugin qtranslate updates its version) and the slider I have at the initial part of all posts is acting wrongly.

Any idea why in the mobile version the slider added by “Metaslider” is not respecting the image proportions and so moving all text below?

BTW, the website is https://www.inandoutbarcelona.net

Thanks a lot!

Andreu
