Thanks for the quick response. I looked through the FAQ. I added the Envira CSS and JS files to the Ignore List:
/wp-content/plugins/envira-gallery/assets/css/envira.css
/wp-content/plugins/envira-gallery/assets/css/responsivelyLazy.css
/wp-content/plugins/envira-gallery/assets/css/justifiedGallery.css
/wp-content/plugins/envira-gallery/assets/js/min/envira-min.js
I’m using WP Super Cache on the site. I deleted the processed files in the Fast Velocity Minify Settings area. When I did that, I think all of the CSS and JS was stripped from the site. Luckily, I went to the WP Super Cache Settings and deleted the expired cache. You did mention in your FAQ that you recommend that I delete the cache in the caching plugin, also.
The Envira Gallery is now showing up fine now. Thanks again for the help.
