That warning is for your own protection; it tries to warn you before you reach the record size limit. Normally this sort of hidden data is caused by copying & pasting from another tool that embeds its own hidden metadata. In your case it looks like maybe CK Editor is adding a bunch of data-cke-saved-href attributes to your links and images (which does nothing on a production website). Itâs also adding a lot of repeated inline style tags for things like font sizes.
Is this copied & pasted from another CMS or website, perhaps?
The quickest workaround would be to run that HTML through something like https://www.htmlwasher.com/ (not affiliated with us; you can use any âhtml cleanerâ or âhtml sanitizerâ you like). Websites like that will clean the HTML into just basic formatting tags. But this may be overly aggressive (such as if you rely on the inline styles for proper formatting).
If none of those work, you might want to check with your web team to see if thereâs some custom sanitizer solution they can make for you, like maybe a custom configuration of sanitize-html to keep the tags that you need and nothing else. It might also help to make use of cleaner CSS formatting with reusable classes instead of repeated inline styles.
Does that help? Please let me know if we can clarify anything
