Problems with jSGCache
Slider only loads at first or second page refreshing, and it doesn’t load anymore, just an empty space will be in it’s place.
jSGCache, which is offered by Siteground hosting company, has an error in their current version (2015.02.12.), that it doesn’t save down our cache files’ incalling, so it doesn’t work with our slider. They will try to fix it in one of the next versions, currently they don’t know where is the problem coming from. Until then consider using one of Joomla’s default caches. The previous part of the documentation could help to decide, which one would be fine for you.
