[HELP] Error Upgrade Helix Ultimate [SOLVED]

[RFSIOS]

Good morning everyone.

Has anyone ever encountered problems while upgrading Helix Ultimate?

Whenever I try, I face the same failure. Even though I import the settings and restore them when the upgrade is complete, I get the page failure message.

Undefined variable $link_color: templates/shaper_helixultimate/scss/theme.scss on line 477, at column 7 Call Stack: #0 import templates/shaper_helixultimate/scss/theme.scss templates/shaper_helixultimate/scss/master.scss on line 8 #1 import templates/shaper_helixultimate/scss/master.scss (unknown file) on line 1​

theme.scss - Line 477 Col 7

}
a {
color: #909196;
&:hover {
color: $link_color;
}
}
