WP Rocket is one of the most popular caching plugins for WordPress, offering a rich set of features and flexibility.
WP Rocket has the ability to combine and minify JavaScript and CSS, generating a separate file for each. Additionally, it collects all inline JS/CSS from the site's HTML code and adds it to the aggregated cached files. This is certainly convenient, but in some cases — especially when used alongside other plugins — it can lead to errors or improper behavior.
