@iaiawebmaster This isn’t likely an issue on the Comet Cache side of things. The Divi theme developers need to make their CSS/JS compatible with compression. If that’s not possible, you can either exclude those CSS/JS files in the HTML Compressor, or disable the HTML Compressor in Comet Cache altogether.
The unnecessary clearing of the cache is also most likely an issue on the Divi side of things: Comet Cache simply listens for certain WordPress Core hooks to determine when the cache should be cleared. If another plugin or theme calls those hooks unnecessarily, that will result in Comet Cache clearing the cache unnecessarily. The Divi theme developers will need to review what WordPress hooks they might be calling inadvertently.
The list of hooks and filters that Comet Cache attaches to can be found here.
