Why are changes not showing up on my WordPress site?
This issue is most often caused by the cache functionality of WordPress. To see your changes, clear your WordPress cache. The cache is located in a folder called /wp-content/cache/. You can delete content of the cache folder either by FTP or via File Manager in Site Tools.
If the changes are still not showing then you can flush the dynamic and memcached caches for your website from Site Tools -> Speed -> Caching.
Finally, clear the cache of your web browser and reload your website.
