There are some common WordPress mistakes that leave you puzzled. The WordPress update and release failure error is one such error. This error occurs not only because of multiple factors, but it also prevents you from publishing and publishing content on your website.

Imagine if you were running a blog or publication on WordPress. You have a large backlog of content that needs to be published. Suddenly, an error is displayed on your post editor. Your operation has stopped; you have been trying to publish-to no avail.

WordPress publish failed error

This can be an important obstacle when you are running continuous website operations. Fortunately, with a few small fixes and proper research, you can immediately go back to the publishing process.

In this article, we will explain how to fix this error on WordPress. To elaborate, we will discuss seven ways to debug and resolve this error.

So, let’s get started.

1. Check Internet connection and site URL

If an update failed error occurs, one of the reasons can be attributed to an internet connection problem.

Suppose you are writing a blog post and your internet connection is interrupted. In this case, WordPress usually cannot save the changes. This situation is rare, but since it does happen, it is worth mentioning.

To resolve this issue, please make sure you have an active internet connection before posting content. You can do this by going to a new tab and searching for content on the Internet. Make sure you are connected to the Internet by visiting other websites in the new browser tab.

If you are sure that there is no problem with the Internet connection, you need to check the URL settings of the site.

From your dashboard, visit the Settings> General tab. From there, you should check your website and WordPress addresses to see if they are correct.

 

The general settings part of the backend.

If the URL and Internet connection are normal and this error is still displayed, then let’s continue troubleshooting.

2. Check REST API status

This may sound a bit technical, but it is not.

WordPress comes with a site health tool. It scans your website and provides you with a detailed report of everything on the website in terms of performance and security.

To check the status of your website through it, please visit Tools> Site Health. View the bottom result and check the REST API status.

If it shows an error or “unexpected result”, then you need to resolve it.

Now, the site health tool will also provide debugging information. When an error occurs in the REST API call, please check whether there is a third-party service that may cause the problem.

3. Enter debugging mode

If changing the editor does not solve the problem, then it’s time to enter debug mode.

For this step, you will need to access your FTP or file manager. Now, you need to make sure to bring their credentials with you. FTP allows you to access files uploaded to your web host and make changes at the server level from there.

In addition, in this step, you will edit the wp-config file. Therefore, you need to know exactly how to edit the wp-config file.

Considering how you will edit at the server level, if something goes wrong, you need to have a backup plan. You can create a manual backup or use a plugin to back up your website. As a side note, don’t delete files unless you are absolutely sure.

Anyway, let’s look at the steps required to enter debug mode:

Access your server via FTP and search for a folder named “WordPress”.

Inside, look for the wp-config.php file.

Use a text editor to open the wp-config.php file. You can use native text editing programs on PC or Mac, but it is recommended that you use programs such as Sublime Text or Notepad++.

After opening the file, write the following code at the very bottom:

define (‘wp_debug’, true);

Make sure to save before exiting the code editor.

Enable WP debugging

After activating the debug mode, please check if the error has been fixed. If it does not display the WordPress update failed error, then just return and convert the definition (‘wp_debug’, true); define (‘wp_debug’, false) to disable the debug mode.

4. Delete the .maintenance file

If the previous process fails, then we should stay on FTP and try other methods. This time, we will delete the .maintenance file from the server.

Open your FTP and access your WordPress files.

Find the WordPress folder, as described in the previous section. After entering, you will have to search for the .maintenance file. Depending on the file manager you use, you can see different files. If you cannot see the file, you can always search for your specific FTP and find the location of the .maintenance file in it.

After finding the .maintenance file, delete it.

Delete maintenance files

This fix only stays active for 10 minutes. In the meantime, check whether changes have been made in the file.

5. Troubleshoot WordPress plugins

If the previous one does not give results, you can try this step.

Visit your WordPress dashboard and from there go to Plugins> Installed Plugins. Right above the list of plugins, you will see a checkbox-checking this checkbox will select all your plugins.

Next, select the “Disable” option from the bulk operation drop-down menu. Click Apply to save the changes.

Disable WP plugin

Now, activate them one by one to check which caused the error on your WordPress site. When you find the culprit, be sure to send the bug report to the developer. This helps them eliminate conflicts that cause errors in future updates.

6. Replace Gutenberg with a classic editor

When WordPress version 5 came out, it was criticized.

The main goal of this criticism is Gutenberg Drag and drop block editor. A significant difference from traditional editors (aka classic editors) is that it takes a while for new users to get used to it.

If you have updated WordPress and see an update/publish failed error, Gutenberg may be the culprit.The first step in debugging this issue is to replace Gutenberg with Classic editor Plugin on WordPress.

From your WordPress dashboard, navigate to the plugin and click Add New. You will then be directed to the WordPress plugin store. It looks like this:

Install classic editor

You should see that Classic Editor is one of the first plug-ins listed. If you don’t see it as an option, just use the search box to find it. Now, install and activate the classic editor.

Replacing Gutenberg with a classic editor may solve this problem. Try to publish your post again and see if it works.

If this change solves the problem, then it’s time to look at the cause. In short, this usually happens when a WordPress page builder or other plugin conflicts with Gutenberg.

important: Installing the classic editor will disable your ability to use Gutenberg to create custom page layouts. We recommend this method only to solve the release or update issue, not to fix it. You need to further check the installed plugins to see which ones may be incompatible with Gutenberg, and contact the developer for help.

If this does not solve the problem, let us look at other possible solutions in this article.

7. Seek help

If none of the above fixes give results, it is time to consult an expert for support.

There may be some issues with the backend or server that caused the error. In this case, your hosting provider can provide you with the most accurate information and fix the error from their end.

The first thing you need to do is to get in touch with your hosting provider. You can choose between email, phone support, or chat support.

The next thing you need to do is to seek support from the WordPress community. There are many places to find help with WordPress. This can take the form of access to WordPress forums, Facebook groups, and other Internet areas.


It is frustrating to see an update or publish failed error on WordPress. Not only does it stop your post-release process, but debugging it itself is a difficult task. Hope that after reading this article, you will be able to analyze and solve this problem.
