Hey Trevor L. Jurgens,

Those PHP Warnings and Notices dont actually slow down your site.

Try using the Optimization plugins recommended in this Article http://themenectar.com/docs/salient/performance-optimization-guide/ and check if that makes a difference . 

Please update to the Latest Salient Theme Version.

The current version of the theme is 15.0.8 and the current version of the page builder is 6.9.1. Salient versions older than v11 won't be compatible with WordPress 5.5.

Here's the documentation on the available methods for updating Salient: http://themenectar.com/docs/salient/updating-salient/#methods Once you've updated that, the update for the included page builder will become available. Note that "Visual Composer" also renamed their plugin on Envato to "WPbakery page builder" a couple of years back.

Here's an update guide on what to expect when jumping many major releases at once: http://themenectar.com/docs/salient/important-salient-update-for-new-envato-requirements/ take a read through before the update, as many things have changed.

Thanks
