Not flushing rewrite rules properly

Incorrect error_reporting value

Disabling debugging uses define('WP_DEBUG', false), flushing rewrite rules with true, and turning off error reporting with 0.

Practice

1. Why is it important to follow proper deployment steps when updating a WordPress site?

easy

A. To make the site load slower

B. To avoid breaking the site and losing data

C. To increase the number of plugins installed

D. To disable all security features temporarily

Solution

1. Step 1: Understand deployment risks

   Improper deployment can cause broken pages or lost data on a WordPress site.

2. Step 2: Recognize the benefit of proper deployment

   Following deployment steps carefully prevents these issues and keeps the site stable.

3. Final Answer:

   To avoid breaking the site and losing data -> Option B

4. Quick Check:

   Proper deployment = avoid site breakage [OK]

Hint: Remember: proper steps keep your site safe and working [OK]

Common Mistakes:

• Thinking deployment only affects speed
• Ignoring data backup before deployment
• Assuming plugins fix deployment issues

2. Which of the following is the correct order for deploying a WordPress update?

easy

A. Update plugins, deploy to live, backup site, test site

B. Deploy to live, update plugins, backup site, test site

C. Test site, deploy to live, backup site, update plugins

D. Backup site, update plugins, test site, deploy to live

Solution

1. Step 1: Identify safe deployment steps

   Backing up the site first protects data before changes.

2. Step 2: Follow update and test before going live

   Updating plugins and testing ensures no errors before deploying live.

3. Final Answer:

   Backup site, update plugins, test site, deploy to live -> Option D

4. Quick Check:

   Backup first, test before live [OK]

Hint: Backup before changes, test before live deployment [OK]

Common Mistakes:

• Deploying live before testing
• Not backing up before updates
• Updating plugins after deployment

3. You deployed a WordPress update without backing up. Suddenly, the site shows errors. What is the likely cause?

medium

A. The update included incompatible plugins causing conflicts

B. The server ran out of disk space unrelated to deployment

C. The site was hacked before deployment

D. The theme was not activated before deployment

Solution

1. Step 1: Analyze deployment without backup

   Without backup, incompatible plugin updates can cause site errors.

2. Step 2: Rule out unrelated causes

   Server disk space or hacking are less likely immediate causes after update.

3. Final Answer:

   The update included incompatible plugins causing conflicts -> Option A

4. Quick Check:

   Errors after update = plugin conflicts [OK]

Hint: Errors after update? Check plugin compatibility first [OK]

Common Mistakes:

• Blaming unrelated server issues
• Ignoring plugin conflicts
• Assuming theme activation fixes errors

4. After deploying a WordPress update, the site crashes. Which step is missing in this deployment process?

medium

A. Changing the site URL in settings

B. Disabling all plugins permanently

C. Backing up the database before deployment

D. Deleting the theme folder

Solution

1. Step 1: Identify missing safety step

   Backing up the database before deployment prevents data loss if errors occur.

2. Step 2: Understand consequences of missing backup

   Without backup, crashes cause data loss and site downtime.

3. Final Answer:

   Backing up the database before deployment -> Option C

4. Quick Check:

   Missing backup = crash risk [OK]

Hint: Always backup database before deploying updates [OK]

Common Mistakes:

• Thinking disabling plugins fixes crashes
• Changing URLs causes crashes, not fixes
• Deleting themes breaks site

5. You want to deploy a major WordPress update with new plugins and theme changes. Which deployment strategy best prevents issues?

hard

A. Use a staging site to test updates, then deploy after backup

B. Update only the theme and ignore plugins

C. Deploy directly on the live site without testing

D. Disable all security plugins before deployment

Solution

1. Step 1: Understand deployment risks for major updates

   Major updates can break the live site if not tested properly.

2. Step 2: Choose a safe deployment strategy

   Using a staging site to test updates and backing up before deploying prevents issues.

3. Final Answer:

   Use a staging site to test updates, then deploy after backup -> Option A

4. Quick Check:

   Staging + backup = safe deployment [OK]

Hint: Test on staging, backup, then deploy live [OK]

Common Mistakes:

• Deploying directly without testing
• Ignoring plugin updates
• Disabling security plugins unnecessarily
