It is very important to keep your WordPress installation up to date.

If a WordPress security release comes out, you will need to update immediately, otherwise your website can get hacked in no time.

As a business owner, you most likely will not have time to do this yourself, and that’s understandable.

Ideally, you would want a team of technically skilled professionals to take care of this.

Not all updates go smoothly, especially for the WordPress websites with many plugins.

Sometimes a plugin that worked fine for a long time all of a sudden doesn’t work after a routine WordPress update.

In this case a maintenance specialist can help to sort the problem.

Also, it is very important to have a proper backup system in place.

Daily backups to a remote server would be the most preferable. If something goes wrong after update, you will be able to restore the site in few minutes.
