WordPress Slider Not Working? Here’s How to Fix It

by Waseem Abbas on April 6, 2019

Is your WordPress slider not working as it should? If your image slider isn’t displaying right, it can make your website look unprofessional. In this guide, we will share why your WordPress slider may not be working, and how you can fix it.

Let’s take a look into these problems and solve them:

1. Slider Images Aren’t Appearing

You may find that your image slider is loaded but the slides are not showing. Sometimes the images are not properly uploaded or your image slider code files may be causing a code conflict.

Images not appearing

If your slider plugin isn’t updated or doesn’t match to your WordPress version, it can also cause a problem with the images. Try simply updating your WordPress and all plugins to the latest versions. It may resolve this issue.

If your images still aren’t appearing, it could be a caching issue. See this guide on how to clear your cache in WordPress to see if that solves the problem.

2. Your Slider Slows Down Your Site

Slow speed site can create multiple issues for a website. Primarily, it provides a bad user experience and it affects your search engine rankings.

However, your image slider can be one of the reasons slowing your site. You should use a simple yet fast image slider plugin for your WordPress site.

We recommend you to check out the 10 reasons to choose Soliloquy as your WordPress slider plugin.

Sliders created with Soliloquy are incredibly fast. You and your site visitors will notice a big difference in your site speed when using Soliloquy.

We created sliders with the same images using other slider plugins and ran speed tests between them. Here are our results:

Meteor 2.32 secs 27 1.2 MB
Revolution Slider 2.25 secs 29 1 MB
LayerSlider 2.12 secs 30 975 KB

As you can see in the above scores, Soliloquy was the fastest loading WordPress slider in our tests.

3. Slider Stuck on Progress Bar

Is your WordPress slider not displaying images? When your WordPress slider shows a progress bar and images are not appearing, it simply means that your slides are not loaded.

Progress Bar

This could be due to a conflict with another plugin. You can deactivate all your plugins and then reactivate them one by one to identify which plugin is creating trouble with your image slider plugin in WordPress. It is recommended that you should deactivate all those plugins that are not in use.

4. Images Displaying in Irregular Sizes

You may have uploaded image slides with different widths and heights. Most of the image slider plugins don’t crop and adjust the images to display perfectly.

Simply edit your images to match the dimensions for all slides. Or, you can use Soliloquy and let it center and scale your slider images automatically.

5. Other Slider Errors

By default, you can’t add an image slider on your WordPress site, so you must be using a plugin. If the slider images are not showing or the WordPress slider is not working, then your plugin needs to be reviewed.

Most common issues with WordPress image slider plugins are files that are too large, not updated with the current WordPress versions, no support from plugin owner, and more.

Having said that, we recommend you to use Soliloquy slider plugin. It is the best image slider plugin that creates beautiful responsive WordPress sliders in few minutes.

    I need a text only slider – no images. I can do it with soliloquy but it looks terrible. Slider is out of html flow (or so it seems). I can add min height to caption bg to display at uniform height, but slider overlaps other content.
    transitions are awful.
    any thoughts?

    My Soliloquy sliders have stopped working in Chrome. The first image appears, but there are no arrows for navigation, and the captions for all the images are jumbled together on top of each other. The sliders work fine in IE and in Firefox, but not in Chrome.
