I get error message (http 500) when attempting to export sliders.  My hosting support team says it is due to PHP version.

My server is Linux and running PHP 7...., we get no errors on 5.6. Is there a fix for this issue?

Here are their comments:

Per our phone conversation regarding the LayerSlider plugin, below is the error message that was being thrown. As I mentioned, I would recommend contacting the plugin developer to see if they have a work around or a version compatible with PHP 7.

Fixed.
