Yes, it’s strange. Anyway, now we have changed that css line in .site-main {margin-top: -32px;}. We achieved the same result but this doesn’t conflict with the plugin. Thank you again for your work!
We found where the error was. It was in this css line:
.site-content {margin-top: -32px;}.
I don’t understand how that could conflict with the plugin but now, at least on our side, it works perfectly on all browsers (including Vivaldi).
It says “no errors”. And, also, we have installed very few plugins (including Jetpack) and none of the them conflict with your plugin (we tried to deactivate them all).
