As part of your website CMS maintenance, checking your website’s security updates and upgrading them is a must to keep hackers out. But you say why- I have a business that is not interesting to hackers and I am not a big corporation? It does not matter, it can happen to any CMS based website!
More times than I can count, security updates are not acted upon and then the site is hacked. I know this because I get the call to fix the site. Look on the plugin page or on your website dashboard to see if you need to make updates to have your website run smoothly and securely. If your site is being maintained by a marketing company, make sure they are keeping your CMS website secure or ask them how to do so (T.Ella Marketing Solutions provides this monthly website support for clients).
Some sites like WordPress are easier to update than other CMS sites such as Drupal. Don’t forget to back up a copy of your site before you make any changes including updates. If there is a problem when an update is made you can always go back to the older version of the website until you figure out what went wrong!
