What are the most common WordPress error codes?

The most frequent WordPress error codes you're likely to encounter are 404, 500, 403, 503, and 502. The 404 "Not Found" error indicates a missing file, page, or invalid link path. 500 "Internal Server Error" signifies a general problem on the hosting server itself. 403 "Forbidden" means improper file permissions are blocking access. 503 "Service Unavailable" indicates the server is overloaded or down. And 502 "Bad Gateway" points to issues with a proxy server involved in fulfilling requests.

Question 2

Why am I suddenly getting a 503 "Service Unavailable" error on my WordPress site?

Accepted Answer

Why am I suddenly getting a 503 "Service Unavailable" error on my WordPress site?

A 503 error typically appears when your hosting server is experiencing issues and is unable to handle website requests temporarily. This could be due to overloaded resources or maintenance downtime. The good news is it's usually a temporary problem that resolves on its own once the hosting provider brings the server back online at normal capacity. If the error persists for an extended time, contact your web host to investigate and allocate more resources to your server.

Question 3

What causes the 404 "Page Not Found" error in WordPress?

Some common triggers for a 404 error are broken links or incorrect URLs, pages or files that have been deleted, changes to site permalinks, bugs from switching themes, problems from site migrations, or invalid link paths in your navigation menus. To resolve, scan your site for broken links, re-upload missing files, and double check permalinks. Also try activating a default theme to check for conflicts.

Accepted Answer

I switched to a new WordPress theme and now get 500 errors. Help!

Switching to a new theme can sometimes cause 500 errors if the theme has bugs or coding errors that conflict with your server environment. Try reverting back to your previous theme as a test. If the 500 errors disappear, it indicates an issue with the new theme's code. Check for an updated version of the theme or reach out to the theme developers for assistance resolving the underlying code problem.

Question 5

What's the difference between a 404 and 403 error in WordPress?

Accepted Answer

What's the difference between a 404 and 403 error in WordPress?

While both indicate content that can't be accessed, 403 means access is forbidden usually due to incorrect file permissions. 404 signifies the content simply couldn't be found on the server after searching for it. Some steps for a 403 error are verifying proper file/folder permissions and checking for plugin conflicts. For 404, troubleshooting includes re-uploading deleted content, fixing broken links, and correcting permalink settings.

Question 6

Accepted Answer

Why does my WordPress site work fine, then show a 500 error?

A website working normally then suddenly displaying 500 errors is usually indicative of a hosting server issue that recently arose. Potential causes include the server being rebooted, a software configuration change, or resources like RAM being exhausted. Check with your hosting provider for any known issues. They can investigate logs to pinpoint what event triggered the 500 errors so it can be promptly corrected.

Some helpful resources include the WordPress developer documentation, the WordPress support forum where you can search for your specific error, and error tracking tools like Query Monitor that provide debugging details.

Question 10

Should I contact a developer whenever I get a strange WordPress error?

Accepted Answer

Should I contact a developer whenever I get a strange WordPress error?

While calling a developer immediately may provide a quick fix, it can be worthwhile spending time trying to resolve it yourself first. Search the specific error in the WordPress forums, disable plugins to check for conflicts, contact your host for server errors, and confirm file permissions. Taking these initial troubleshooting steps will boost your WordPress skills for handling issues independently down the road. However, for complex recurring errors, professional assistance can efficiently uncover and rectify the source of the problem.
