If you’re encountering the error message “Publishing failed. Could not update post in the database” in WordPress, the solution might be simpler than you think. One of the most common causes of this error is the use of emojis in the post content.
WordPress databases, depending on their configuration, may not support the storage of emojis or special characters correctly. When you try to save or publish a post containing emojis, the database may reject the content, resulting in the publishing error.
Solution: Remove Emojis from Your Post
- Open the post that is causing the error.
- Look through the content carefully and remove any emojis or special characters.
- Try publishing or updating the post again.
Once the emojis are removed, WordPress should be able to update the database and save the post without any errors.
Why Does This Happen?
This issue typically arises when the database uses the utf8 character set, which doesn’t fully support emojis. To avoid this issue in the future, you can consider changing the database character set to utf8mb4, which supports emojis and a wider range of characters.
If you continue to experience this error even after removing emojis, you may need to check for plugin conflicts, database corruption, or insufficient PHP memory, but in most cases, removing emojis resolves the issue.
