If you have added custom code to your site that's impacting its performance or preventing you from editing it, it is most likely due to the code not being formatted correctly or not being HTTPS compliant.
Solution
The following can help you troubleshoot your custom code issues:
Restore a backup of your site to a point before the custom code was added (even if you haven't created a backup, the editor creates one for you when you publish or enter developer mode)
Access Developer Mode to fix the issue manually
Load the non-secured version of the editor to load scripts that were not embedded via a secure connection. To do so, log into http://my.Website Builder.co?nossl
If you are unable to access the editor when your site loads initially, try accessing your editor on a new page by entering a different URL in your editor link, such as https://my.Website Builder.co/home/site/XXXXXXX/about. When you get there, you can delete and re-add the page that is causing problems, or access developer mode to fix the issue on the site's code
If you have any links in your code (http:// or //) and your site is using HTTPS or you're in the preview, then you will have to change it to https:// instead
Warning
Consent management apps are not able to prevent code from running prior to consent when the code is placed in the header HTML. This is because Website Builder optimizes the structure and order of how content loads, based on performance best practices on the site. We place scripts and CMP banners lower on the page, in order to improve the performance of primary content. Because of this, it is recommended to place code in the body-end when using a consent management app.
