Can you please re-create the following pages on the website :
Hi sachinsehdev
Are you using latest version of JA Builder? We released new version to fix this issue: https://www.joomlart.com/blog/joomla-extensions/important-ja-page-builder-updated-for-storing-page-builder-data-in-your-site-s-database
Please BACKUP your site first, then download 3 packages here: https://www.joomlart.com/member/downloads/joomlart/ja-joomla-page-builder/ja-joomla-builder including: package + component + plugin, download them individually and install into your site.
Next, try to go to edit mode of a page (don't publish anything), just compare it with frontend of that page and see how it looks.
If they looks the same, then you can edit it normally.
Regards
saguaros Thank you so much
