Hello, Bilal Hussain,
We suggest increasing the “Max execution time” to 600 or 1000 and the “Max input vars” to 2000, and then checking back with editing WP Bakery. If this does not resolve the issue, we recommend disabling all third-party plugins (including cache plugins) that do not come bundled with XStore (https://xstore.helpscoutdocs.com/article/36-included-plugins), clearing the cache of the browser, and then checking again. It is possible that one of the additional plugins is causing the issue.
If the issue persists, please keep all third-party plugins deactivated on your site and grant permission to debug your site, which includes deactivating all third-party plugins and on-site Customization. Please note that you should take a complete backup of your site first.
We hope this helps.
Best Regards,
8Theme’s Team
