21 How do I change my password?
If you are already logged into your WordPress account, click on your username in the admin tool bar at top right corner of the screen (if your admin bar is disable, then simply go to Users > Your Username via the dashboard).
Scroll to the bottom of the screen and click the option to reset your password. Write down your password or add it to your login app (such as 1Pass) then save.
If you’re locked out of your account go to your login page (usually at yourwebsite.url/wp-admin), click on the “Lost your password?” link and following the instructions to reset your password via email.
And if for some reason neither of those methods work, you can recover your password manually via phpMyAdmin or mySQL (but we only recommend this if you are comfortable with coding).

When working on a post, click the link to “Set featured image” in the “Featured Image” meta box. This will open your media library. Either select an image or upload a new one and save.

27 Will my website slow down if I install too many plugins?
We see this question a LOT and the answer is maybe. The issue typically isn’t with the number of plugins you install but rather the size, function and quality of the plugins.
- Large plugins: Everything but the kitchen sink plugins typically include features for just about everything which makes plugin management easy for you as the user, but it could slow your website down as the more a single plugin does then the more resources it will require.
- Plugin conflicts: The top issues we see related to plugins are incompatibility or duplicate features. Some plugins simply don’t work when installed on the same website (for example, WooCommerce does not work with W3 Total Cache). Similarly, you really should avoid duplicate functionality. You only need one slider plugin, one SEO plugin, one security plugin, etc.
- Poor quality: You may come across a plugin that sounds great but once installed slows or brings your website down to a halt completely. Unfortunately, there are a lot of poorly coded plugins floating around the web, which is why we always recommend using plugins for reputable sources
