Nevermind I figured it out 🙂
In case anyone have the same problem here’s what I did.
I looked around under style.css, copied the code:
body.responsive.layout-full #page-wrapper .full-container {
margin-left: auto;
margin-right: auto;
max-width: 1080px;
}
Then I pasted the code on my child theme style.css and changed the max-width: to 1250px in my case. In yours just play around and don’t be scared 🙂
Much luck! Cheers 🙂
Im using a theme called vantage. Unfortunately I cannot remember exacly where I downloaded it from, anyway most things seem to be working properly besides the menu width being too small. Any suggestions on how to fix this?
