WP-Optimize is a popular plugin that helps you boost site performance and reduce page load times. This guide has tips for troubleshooting issues if you are using MetaSlider with the WP-Optimize plugin.
If you are using the WP-Optimize plugin on your site and the slideshow is not updating, check the “Cache” settings. Under the “Advanced settings” tab, try using the “List paths” area to exclude any pages with MetaSlider slideshows.
If you are using the WP-Optimize plugin on your site and the slideshow is not loading, check the “Minify” settings. Under the “Javascript” and “CSS” tabs, try excluding these CSS files:
/wp-content/plugins/ml-slider/assets/sliders/flexslider/flexslider.css
/wp-content/plugins/ml-slider/assets/metaslider/public.css
And also try excluding these Javascript files:
/wp-content/plugins/ml-slider/assets/metaslider/script.min.js
/wp-content/plugins/ml-slider/assets/easing/jQuery.easing.min.js
/wp-content/plugins/ml-slider/assets/sliders/flexslider/jquery.flexslider.min.js
