How is that possible? What did I miss? Is a web server updated a few days ago, the update is about PHP which is very important for a web server. What can I do? What should I do? Will they update later along with other updates? Is this behavior normal after a few days from the version update? My server is in Vultr, maybe something is missing in Vultr?
