Browser cache problems
– Slider isn’t visible or working properly, unless Ctrl+F5 (hard refresh) is pressed.
This can happen, when the Joomla cache is turned on, and in the Extensions → Plugin Manager → System – Cache → Use Browser Caching is turned on. It’s usually working with our sliders, but it can trigger an error in another extension, which can make ours stop. You should just turn it off, it doesn’t really give that much extra speed, and it’s a common error causer.
