Background images disappear after 2 seconds on Chrome 67
Hello,since a few days, i've a problem with background parallax images.
On some websites using betheme, the background parallax image appear for 1 or 2 seconds and it disappear.
There isn't any error message in the console but when i desactivate the packaged Revolution Slider plugin, it works correctly.
Everything is up to date (WordPress, Betheme and Revolution Slider).
Can you help me with that please ?
Thanks by advance
