I realise this issue may have appeared several years ago but this was before changes.
Up until recently my site hosted by 000etc played flash photo galleries produced in Webplus X8. Today the galleries are not showing when I upload them. I thought at first it was something I needed to do but they play perfectly well in Internet Explorer but not in Edge. Edge has its Flash Player enabled.
I think this issue is not related to 000webhost as it works on other browsers, this may be something related to microsoft edge, and webplus X8.
Maybe they can help you more @akhilkumar332@NGINX
