The WP Before After Image Slider is a powerful WordPress plugin that allows users to create interactive visual comparisons on their websites. However, like any plugin, users may encounter issues during installation, setup, or use. This troubleshooting guide addresses common problems and provides solutions to ensure your slider functions smoothly.

Common Issues and Solutions

1. Slider Not Displaying

• Possible Causes:
  • Shortcode errors
  • Plugin conflicts
  • Theme compatibility issues
• Solutions:
  1. Verify Shortcode: Ensure the shortcode is correctly placed in the post or page. It should look something like [before_after_slider id="123"].
  2. Check Plugin Conflicts: Deactivate other plugins individually to identify any conflicts. Reactivate them after testing.
  3. Theme Compatibility: Switch to a default WordPress theme (like Twenty Twenty-One) to see if the issue persists. If the slider works, your theme may be the problem.

2. Images Not Loading

• Possible Causes:
  • Incorrect image URLs
  • Large image file sizes
  • Image format issues
• Solutions:
  1. Check URLs: Make sure the images are correctly uploaded and the URLs are correct.
  2. Optimize Images: Use image optimization tools to reduce file sizes without compromising quality.
  3. Use Supported Formats: Ensure images are in formats supported by all browsers, such as JPEG or PNG.

3. Slider Not Responsive

• Possible Causes:
  • Incorrect responsive settings
  • CSS conflicts
• Solutions:
  1. Responsive Settings: Go to the slider settings and ensure responsive design options are enabled.
