Hello victia,
Thank you so much for using our theme. As per your questions it seems that it’t due to the plugin conflicts. Would you please check once by deactivating the installed plugin one by one and check it. If our demo is working fine, then you need to check your site once and please check your issues with multiple browsers as well.
Hope, it will solve your issues. Let us know, if you can”t able to solve it.
Warm Regards
