As more and more people have started using WordPress as the default CMS for their websites, the complaints regarding WordPress customisation errors have also increased.

Without the right tools, often it is difficult to customize a layout. However, WordPress has allowed anyone to create, customize, and manage their website without hiring a website developer. Users can add page builder plugins to make as many changes as they want to the layout, functionality, and even the user experience.

But often themes are rigid and don’t come with proper documentation. Often customization errors popup and users have little or no experience in handling them. Unless an experienced developer is hired, these errors leave the website down and this hurts users’ digital business.

Common WordPress Customization Errors & Solutions

In this article, we are going to discuss some of the most common WordPress customization errors and their possible solutions to make your website management easy and simple.

Let’s get started.

1. Missing Style Sheet?!

Imagine you purchased a new theme from the internet. The theme comes packed with all the necessary templates that you need to make changes to your website. It is easy to use. Superfast. Lightweight. And allows you to try unlimited layouts.

Great right?

So, you download the theme and then upload it on your website and guess what? You get the error ‘Missing Style Sheet’!

Now what?

The theme installation failed and you think you were ripped off by the developer.

Although this might be true and there is a possibility that the developer may have ripped you off. But, if you bought the theme from a reliable store like Envato, Themeisle, Theme forest, and many others similar then you don’t have to worry at all. Because these themes are insured, and developers are liable to answer your queries.

Now, before you come to that conclusion, it is important that you check if the theme folder missed the style sheet or if you uploaded the wrong theme folder. Usually, you have to upload the main directory to the WordPress folder. If you upload the subdirectory and it doesn’t include the stylesheet, then you will get the stylesheet error.

2. Homepage Doesn’t Look Like Website Demo Page

In some cases, you download a theme thinking that you will get the same layout that the website demo shows but that doesn’t happen, don’t worry. Here are a few ways to get actually the same page as website demo as your home page.

– First, check if you have selected ‘Home’ in the settings menu.

Frontpage settings

Most website owners keep the blog page as the home page and then complain that the website theme doesn’t work as the demo theme. You will need to change the front page to ‘Home’ and the posts page as the ‘Blog’ page to make the theme work properly.

– Change the website template for the page that you want to keep as your home page. If the template of the home page is different from the one that the demo theme page uses, then you won’t get the same layout.

Now try refreshing your website. You will see that the homepage now shows the exact same layout as the website demo page.

Note: Most themes come with proper documentation. Read them to properly optimize your website layout.

3. Menu Doesn’t Show in WordPress

If you are not seeing the menu you created on the website homepage, then you may have not properly added it to the layout. To check if that is true, go to Appearance > Menu.

Now see if you have the menu available. If the menu is available, then you have just selected the right settings for it.

In some themes, the menu settings are available below the menu structure. However, in other themes, the menu settings are available in the ‘Manage Locations’ section.

You will have to check both to see where the ‘Menu Settings’ window is available for your selected theme. Now make changes to it accordingly.

4. Sliders, Tabs, & Accordions Not Working

If the sliders, tabs and accordions on your website are not working after installing a new theme, then here is what you need to do.

  • Make sure that your theme doesn’t require an additional plugin to make the sliders work properly. If it does, install them. You will get a note on your WordPress dashboard if the theme requires additional plugins.
  • Purge cache on your website. You can use any cache plugin to purge cache on your website. This could be WPRocket, WP Total Cache, or any other that you like
  • If your WordPress theme comes with a settings panel, locate it on your dashboard. There will be a settings button to manage the sliders and accordions available on your theme.

5. All Posts Return 404 Error

A 404 error is pretty common especially when you have installed a new theme on your website. Often themes change the permalink structure of your website. The links then start showing the 404 error. To fix this problem, go to WordPress dashboard > Settings > Permalinks > Post Name.

permalink settings

Now try again and see if your pages load as they were supposed to. If your pages still don’t load. You will need to rename the .htaccess file through your website cPanel. The .htaccess file keeps a track of all the changes on your website.

Once you have renamed the .htaccess file, go to WordPress settings and then on permalinks. Reselect Post name and click on Save.

This will create a new .htaccess file for your website. Now refresh your website pages and they will show as normal.

6. WordPress Memory Limit Exhausted

Another common issue with WordPress customizations is the memory limit. When you are uploading images, videos, or files more than 64MB in size, you get the ‘Memory limit Exhausted’ file error. Here is how to fix this problem.

– Go to cPanel. Open the public_html folder, and then locate the wp-config.php file. Now change the memory limit to 256M

define( ‘WP_MEMORY_LIMIT’, ‘256M’ );

The above setting will change the WordPress image and file limit to 256MBs. Now try to upload the same file again and you will see that the error disappears.

If you don’t have access to the cPanel, you can ask your website hosting provider to change the WP Memory Limit for your website.
