SiteOrigin CSS Error

Hi

I am getting the error on the SiteOrigin CSS Editor:

“”fatal error, cannot continue: null is not an object (evaluating ‘r.getLine’)”

I see there is already another thread on this.

I have tried disabling the plugins as suggested, but still no luck.

My site hosted locally on my computer using MAMP at the moment. Im using the Vantage Premium theme.

Please let me know if there is anything else I can try?

Cheers,
Mike
