Enabling Plugin: Shortcodes by UnitedThemes - sends site to 504 Gateway Time-out (WordPress v5.9.2)

Deploying site: www.stasborukhoff.com under Linux environment with WordPress 5.9.2.
But are unable to bring the site up.

Enabling Plugin: Shortcodes by UnitedThemes, makes the site go down with: 504 Gateway Time-out and fails to update changes after changes from Editing Page Builder.

Tried enabling Plugin “Envato Market” but that fails with a message “You do not have sufficient permissions to delete transients”.

Please suggest how to resolve.

Hi @Stas27,

this error generated most probably by the PHP max execution time limit or by the FastCGI read timeout settings. please contact your hosting provider and let them know. They will check it through error log and will assist you. If hosting provider let you know that error is coming from your purchased item then Contact the Author of your purchased item. Contact Author and let them know.

Thanks
