Sorry to hear of the problem you are having.
Could you please temporary disable WP-Super-Cache and autoptimize cache on your site so that I can troubleshoot it?
Also please make sure you are using below latest version of theme and plugins on your site.
Please login to access this file
This can be due to plugin conflict on your site so please try temporary deactivating all plugins except Unyson plugin and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
thanks for your reply!
I use jevelin 2.8 since yesterday (download envato). I disabled Autooptimize and Supercache yet
A few days ago i switches off all plugins that are not delivered with jevelin, still the same problem.
I hope you have a solution
i thought the problem was solved, but that was not the case! Still the parallax problem with Edge in IE11, see https://www.201-photography.de
I have disabled all plugins that are not included and deleted my own CSS files. Always the same! Firefox, Chrome etc. no problems.
I hope you have a solution!
