Warning: Cannot use a scalar value as an array in /wp-content/plugins/cornerstone/includes/classes/components/class-shortcode-finder.php on line 91

Hi there, recently my client’s site is getting this error on the front-end:

“Warning: Cannot use a scalar value as an array in /wp-content/plugins/cornerstone/includes/classes/components/class-shortcode-finder.php on line 91”

I have tried to disable errors via wp-config, but that isn’t working.

Any idea what I need to do?

Hi Drijen,

Thank you for reaching out to us. Can you please check for the following first:

1. Ensure everything is up to date according to our version compatibility list at https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195. Please follow the best practices when updating your theme and plugins. See https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62 for more details.

2. If you’re using a caching plugin, clear all caches including browser cache then deactivate your caching plugin and other optimization plugins.If you’re using a CDN, please clear the CDN’s cache and disable optimization services.

3. Test for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.

4. Deactivate your child theme and switch to parent theme.

If you still have problems kindly get back to us with the result of the steps above and URL/User/Pass of your WordPress dashboard using the Secure Note functionality of the post to follow up the case.

Thanks.
