Since 1.4.1 my title is messed up twice

Pretty sure the solution will result in finding some title code in your theme and deleting it. Might ask your theme company forums where you remove the homepage title since you’re now using Yoast WordPress SEO. I believe Google doesn’t pick up on it so that’s good, just your theme making the tabs title look funky. I was upset until I found the code on my theme and now the plugin works exactly as it should. Worth removing that extra code.

Yes that’d be a fix, however deleting it maybe strong, just ‘comment’ it out in the code so its omitted from parsing.
