On some websites you may see an arrow in the bottom left or right corner. When you click this, it jumps you back up to the top of the page with one click. This is helpful on pages with long form content, or infinite scroll, so that you don’t have to manually scroll back to the top of the page.
The “destination folder already exists” message will show up in your WordPress dashboard if you try to install a theme or a plugin that already exists on the server.

But, in brief, when you install a plugin or theme, a folder on your server is created.
So if you try to upload the same plugin or theme again, there will already be a folder with the same name, and that creates a conflict – you can’t have more than 1 folder in the same location with the same name.
It’s a good practice to remove unused themes so that you don’t have to maintain them with updates for security purposes.
If a theme is installed on your site, it means all the files still exist on your server. That means the code could still be exploited, even if the theme isn’t active. So you either have to maintain the updates for the theme, or you should just remove it.
If you write long tutorials and guides, a table of contents can help your readers more easily navigate, get a sense of the content that’s coming, and find what they are looking for.
Here are a couple of plugins I like for adding a table of contents to posts.
Most WordPress site owners will see the recommendation to “remove unused Javascript” when they run a PageSpeed test.
The technically complete solution is out of reach for most site owners, but there is an effective shortcut solution that I share below.
JavaScript (JS) is a type of code used on website mostly for interactive elements like sliders, animations etc. Compared to CSS or images, it is much more resource intensive so it takes longer to process when your page is loading. It’s especially bad for mobile performance.
For best performance, you should aim to have as little JavaScript as possible on your site.
Loading JavaScript that isn’t even used on the page is a waste of resources and processing power, and that’s what this PageSpeed recommendation is getting at.
If you’ve ever run a PageSpeed or other speed test for the mobile version of your site, you’ve undoubtedly been horrified by the low speed and score compared to the desktop version of your site.
In this post I’ll explain:
Optimizing for mobile does take a bit of extra effort since site owners are usually “retrofitting” their sites for mobile performance.
If you are starting a new site, it will be easier if you consider mobile performance from the start, and make it a priority.
