Can't edit the header on my blog

You have a number of javascript errors when loading the page.

Your theme is a commercial theme and you should try support or an upgrade here, https://themetix.com/sermo/ Sorry, I do not see a support link on that page.

Forum volunteers are also not given access to commercial products, so they would not know why it is not working properly. Other community members who may have faced your issue might be able to help you but your best bet is your product’s developer. Keep in mind we encourage you to use the official support venues, as it allows the developers to be aware of issues with their code and gives back to the community in a more robust way.

It’s actually not a commercial theme, it was custom developed by me and a front end developer. The javascript errors related to https are actually what I’m trying to fix by editing the page.

`<div class=”hero-content”>
<h3><img class=” alignleft” src=”https://speakerlauncher.com/wp-content/uploads/2015/07/neen-james1.png&#8221; alt=””>Neen James <span style=”color: #999999;”>@neenjames</span></h3>
<h4><span style=”color: #60abb5;”>Author of Be AH-Mazing??</span></h4>

Should be editable under hero content maybe in the theme or in header.php? Hard to tell. Custom themes are like commercial. We don’t have them.

That’s the code for it. I can edit the header in the theme on all of the other pages, that’s how it’s designed. Once I’ve made that the posts page, though, I can’t edit it. I can delete all of that code from the header in the theme and nothing happens. I’ve checked it and none of that is hard-coded anywhere.

So when you do a site search for BRILLIANT it is no where?

Exactly. When I search the theme files none of that shows up.

Have you tried:
-deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
-switching to the default theme to rule out any theme-specific problems.

Well an update on this…tried swapping out for the 2016 theme and everything went haywire. It reset all of the CSS I had in Jetpack and some other things. I think I need to put this site on a staging url and give it a full scrub down. I’ll post an update here when I get it hammered out. kmessinger, thank you for all of your suggestions.
