Avada Fusion 4.0.3 / Firefox 61.0.2 / php 5.6 / WP 4.9.8
In theme options I can see some but not all.
By example: “Header Styling”. When I click here, the system shows me for 2 seconds the options then appears a green mask (gray in other options) covering the options. If I move the mouse over this green area can see the alternate text like “select color” , the options are there but masked. ) Of course can’t change any.
Other options like “Logo” or “Layout” can handle without a problema.
Any help is welcome.
