Cornerstone is not adding section boxes in order to add elements and it shows the following message error when cornerstone loads:
The preview HTML did not include a closing ; tag. It may fail to load or work properly.
This may or may not be the cause of why cornerstone does not show the section box in order to add elements when a new section and row are added.
Help please?
Hi @ivansalasj,
Thanks for writing in!
Seems like you have a invalid HTML tag in your content that you have add in the page.
How ever we can’t confirm this without checking the website.
Before sending us the details please check this following.
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. Clear all caches including browser cache then deactivate your caching plugins and other optimization plugins.
3. If you’re using a CDN, please clear the CDN’s cache and disable optimization services.
4. 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.
5. Custom code syntax error. If you have a child theme, please enable the child theme and check if the issue still exists. If you have entered any custom JS or CSS into their respective editors. Please review the code for any syntax errors. A mis-placed semi-colon or a missing bracket will cause the issue you’re seeing.
If you could please try the above and if you still have the issue we’d be more than happy to assist.
