Unless the iframe source is from your own website, you don’t have any control over response. Is this only an issue with preview? The published pages seem to be OK AFAICT. If so, the error might be due to how your editor manages previews. You might choose to ignore the problem. If it’s bothersome, I recommend seeking assistance through the dedicated support channel for your editor.
Hi there,
Thank you for your response. This is only an issue with preview. I cannot edit pages through our ThemeCo account. Do you know where I can find a validation key for the theme purchased? I am taking over web design for a previous employee and nothing was marked down. If you can provide any information regarding this, I would greatly appreciate it.
Again, we are working with ThemeCo X and cannot edit through Cornerstone.
Thanks!
