You need to make sure that you delete any themes or even any plugins that you are not using at the moment. You also need to try and limit the amount of plugins that you have installed in the first place as well and the main reason for this is because the more plugins you have, the more vulnerable your site is in general.
Don’t Download Free Premium Plugins
If you download free premium plugins then this may seem like a great way for you to save money. The problem is that a lot of them are not official and you may not even be getting what you paid for. Now more than ever, it’s important that you don’t buy your plugins from anywhere other than where they are for sale.
If you have a very old version of WordPress running, you may find that the security flaws that you have are common knowledge to every hacker out there. When hackers have this information they are able to target your site and there isn’t much you can do about it. To avoid this, always make sure that you have the latest software update installed.
So there are plenty of ways for you to keep your site secure, and it is now more important than ever for you to try and do so.
