Managing Divi theme's cache
One of the most popular WordPress themes, Divi, has built-in caching features. Custom caching solutions in addition to the ones Seravo provides may cause issues on some sites. You should know how to manage the caching settings to investigate the problems they might a cause to.
Clearing Divi cache
The way Divi caches CSS is by generating a static file of them. That's a very efficient way to improve your sites performance as static files are taken care of by HTTP level caching but the file might not include the changes you've made after the file was generated. The solution to this is deleting the file so it can be regenerated.
If you have static CSS file generating on, you can delete them by logging in to your WordPress site and by opening Theme options -page under the Divi menu. You can find the Clear button for static CSS file generation under the Builder tab's advanced options.
