Add great content to your posts automatically: just choose a city and get a map, photos, data, and related articles. Very useful for travel bloggers!
The cache last for 2 days, after two days it will read the feed again for that city, if you want to delete the cache it is in the folder called "cache" in the plugin's directory ("/wp-content/plugins/100-cities/cache/")
This will occur the first time you publish a post (as the plugin is accumulating the data for the first time). Double check point 8 of the installation process to make sure the writing permissions for the cache folder are turned on and if it is on, don't worry be happy, our plugin is not slowing down your website.
