PHP Notice: Undefined index: selector in /wp-content/themes/pro/cornerstone/includes/classes/Documents/Content.php on line 90

Hi, I’m running into this issue on a multisite install we have. I manually updated the theme to make sure that it didn’t lock up with the 6.2 update. I’m still on 6.1.1 for this install but when I try and access Cornerstone I get the above error. This hasn’t happened on any of the other sites we run this theme on. For clarification on the multisite, the client just wanted subdomains for careers and volunteers and stuff. This isn’t a site where anyone can just add a subdomain.

Any assistance would be appreciated!!

This is what I see when I try and load it:

Hi @adsmedia,

I have checked your website and found the issue you described here. I suspect that it might be due to an improper update of Pro, I would suggest you deactivate and delete the Pro and re-install the version by downloading from your Themeco account and check if that resolves your issue. If that does not help, there might be some different reasons behind your issue. I would like to suggest troubleshooting the following common issue to help us to recognize the reason.

1. Theme Related Issue
2. Plugin Conflict
3. Theme Update related issue
4. Child Theme Related issue
5. CSS/JS Customization
6. Disabling Cache
7. Disabling CDN

If you discover that an issue is coming from a custom code or 3rd party plugin, kindly consult with a developer or contact the plugin author. Please note that we do not provide support for custom codes and 3rd party plugins.
If none of the above helps, please copy your live site to a staging server so we could troubleshoot freely without breaking your live site.
And give us access in the secure note including:

– WordPress Site URL & Login URL
– WordPress Admin username/password

To create a secure note, click the key icon underneath any of your posts.

Thanks
