Steps to Changing WordPress Theme
Now, let’s start with one of the most crucial steps in learning how to change WordPress theme, which is backing everything up.
Step #1: Backup Everything (This is CRITICAL)
Warning: Never change themes without a backup. I've seen too many sites crash because people skipped this step.
Here's the deal:
When you learn how to change WordPress theme, backing up is your safety net.
- Install a backup plugin like UpdraftPlus
- Create a full site backup (files + database)
- Store it offsite (Google Drive, Dropbox, etc.)
Pro Tip: Test your backup by restoring it on a staging site. A backup that doesn't work is useless.
Step #2: Set Up a Staging Site
This is where the magic happens.
A staging site lets you test your new theme without affecting your live site. It's like having a practice room for your website.
Here's how to create one:
Method 1: Use Your Host's Staging Feature
Most hosts (SiteGround, Bluehost, etc.) offer one-click staging.
Method 2: Use WP Staging Plugin
Install WP Staging, click "Create New Staging Site," and you're done.
Step #3: Choose Your New Theme Strategically
Not all themes are created equal.
When figuring out how to change WordPress theme effectively, theme selection matters MORE than the actual switching process.
Here's what to look for:
- Fast loading speed (use GTmetrix to test demo sites)
- Mobile responsive (60% of traffic is mobile)
- Regular updates (updated within last 3 months)
- Good reviews (4+ stars, recent reviews)
- Plugin compatibility (especially with your essential plugins)
My Recommendation: Stick with themes from reputable developers like Astra, GeneratePress, or OceanWP.
Step #4: Document Your Current Setup
Before you change anything, document what you have.
This step saves hours of headaches later.
- Screenshot your current widget areas
- Copy custom CSS from Appearance > Customize > Additional CSS
- Note your menu locations
- Save any custom code from functions.php
Step #5: Install Your New Theme
Now for the main event.
Here's exactly how to change WordPress theme step-by-step:
For Free Themes:
- Go to Appearance > Themes
- Click "Add New Theme"
- Search for your theme
- Click "Install" then "Activate".
For Premium Themes:
- Download the theme ZIP file
- Go to Appearance > Themes > Add New Theme
- Click "Upload Theme"
- Select your ZIP file and install
Step #6: Reconfigure Everything
Your site probably looks broken right now.
Don't panic. This is normal when you how to change WordPress theme.
Here's your cleanup checklist:
1. Fix Your Menus
Go to Appearance > Menus > Manage Locations and reassign your menus.
2. Reset Your Widgets
Drag widgets from "Inactive Widgets" back to their proper locations.
3. Recreate Your Homepage
If your homepage looks weird, go to Settings > Reading and set it up again.
4. Add Your Custom CSS
Paste your saved CSS into Appearance > Customize > Additional CSS.
Step #7: Test Everything
This is the most important step.
Test your site like your business depends on it (because it does).
Check these critical areas:
- All pages load correctly
- Contact forms work
- Shopping cart functions (if applicable)
- Mobile responsiveness
- Page speed (use PageSpeed Insights)
- SEO elements (titles, meta descriptions)
Step #8: Go Live and Monitor
Ready to make the switch on your live site?
Here's how to change WordPress theme on production:
- Repeat the installation process on your live site
- Clear all caches (hosting, CDN, plugins)
- Monitor for 24-48 hours
- Check Google Search Console for errors
Important: Don't delete your old theme immediately. Keep it for at least a week as a backup.
Common Issues (And How to Fix Them)
Even when you know how to change WordPress theme properly, things can go wrong.
Here are the most common issues:
1. White Screen of Death
Solution: Switch back to your old theme and check error logs.
2. Broken Layout
Solution: Clear all caches and check for plugin conflicts.
3. Missing Content
Solution: Your content is still there. Check widgets and menu assignments.
Emergency Fix: If everything breaks, restore your backup and start over. It's faster than trying to fix a broken site.
SEO Considerations
Changing themes can impact your SEO.
Here's how to protect your rankings when learning how to change WordPress theme:
- Check that search engines can still index your site (Settings > Reading)
- Verify your permalink structure hasn't changed
- Test page loading speeds
- Ensure meta tags are still in place
- Submit an updated sitemap to Google
