Upfront custom theme not working

Having an issue getting a custom theme to load in Upfront Builder. If one of the upfront themes is opened in Builder it loads fine, but custom themes load continuously with some error.

    Hi Dmitris,

    I logged in this morning, deleted the existing themes (except for the starter them from Upfront) and attempted to create a new theme...and no luck.

    Using Google Chrome Dev Tools I can see the following error in the console:

    Uncaught SyntaxError: Unexpected token )
        at new Function (<anonymous>)
        at v.template (main-1.9.4.js:88)

    I'm using Windows 10 with Google Chrome as my primary browser, though I've also tried both Edge and Firefox in the past.

    Hello there Dave Mackey,

    hope you're doing good today! :slight_smile:

    I've just pinged another colleague of mine, who works on Windows and he was able to create a new child theme using Chrome, still with no problem at all.

    I guess that this is happening due to some browser cache and/or browser extensions.

    Could you please follow next guide to clear browser cache
    and then try to create a new UF child theme under a incognito browser window, so extensions are deactivated.

    Let us know how that goes!
    Warm regards,

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
