WordPress is an efficient website and blogging platform used by over 43% of web users worldwide, making content creation and publication simpler than ever.
But sometimes things go awry and an Invalid JSON Error may occur on WordPress. Thankfully, however, this issue can be easily remedied.
1. Check the.htaccess file
As anyone can attest, the Invalid JSON Error in WordPress can be extremely frustrating. Not only will it prevent you from working on your website, but identifying its cause is often difficult as well. But don’t despair: many solutions exist to address the issue – some even beginner-friendly so you don’t risk losing any data in testing out these solutions!
As soon as an Invalid JSON Error occurs, the first thing you should do to resolve it is review your.htaccess file – an Apache configuration file where many server configurations reside – as it could contain incorrect settings that cause the problem. If unsure, reach out to your hosting provider to get more guidance or contact your website designer/host for support.
For easy access, the.htaccess file typically resides at the root directory of your website. To do so, either using FTP client software or your WordPress hosting account dashboard login credentials, download and save to computer as a backup before editing using code editor and upload back.
Once this has been accomplished, attempt to recreate the error. If it persists, one of your plugins could be responsible. To identify which one it is, go to “Plugins – Installed Plugins”, select all plugins, then go into Bulk Actions menu and deactivate them one at a time until one stands out as being the offender.
After deactivating all plugins, try recreating the error by deactivating each of them one at a time until you identify which plugin is causing it. When this has been accomplished, contact its author for support or switch out for another option.
2. Check the permalink settings
WordPress updates require communication between itself and the server; when making updates to posts or pages, WordPress expects a response in JSON format (JavaScript can read JSON data directly), but when this doesn’t happen it displays “The response was not valid” error message due to incorrect URL settings in WordPress or broken permalink structures. To troubleshoot this problem first perform a basic checkup of your site by reviewing when last core and plugin updates were performed as well as changes in permalink structure since then.
First, open up the WordPress Admin dashboard and review Permalinks Settings. Choose a suitable permalink type that suits your website before saving changes – this should resynchronise permalink structures on both ends with server side changes, potentially solving Invalid JSON Error issues.
If this doesn’t solve the issue, you may need to switch back to your old permalink structure by accessing Tools > Site Health in WordPress dashboard and selecting Reset Permalinks option.
Another possibility could be that your web hosting server’s permalinks have been incorrectly configured, which you can check by visiting the WordPress Admin Dashboard and selecting one of the available permalink options. If this does not help, contact your provider for further assistance.
Errors may occur due to insufficient user permissions; that is, one user does not have permissions to access and modify files that are being updated in WordPress. To fix this, check that all relevant users belong to an appropriate role with sufficient privileges for them to access and update content as necessary.
While Invalid JSON errors can be frustrating, they’re relatively straightforward to resolve. By following this article’s advice on resolving them, you can ensure your WordPress website is functioning without errors or glitches. If any further assistance is required, consider consulting a dedicated WordPress development company; their experts can quickly assess your site piecemeal and pinpoint the cause of an error quickly.
3. Check the theme
An Invalid JSON Error in WordPress occurs when there is an issue between client and server when exchanging data, leading to problems for creating posts or updating content, among other tasks. To solve the issue and troubleshoot its cause, several things can be done; these include inspecting your.htaccess file, permalink settings and plugins as well as your media file for corruption or misconfiguration in some instances.
First step should be checking your permalink settings of your website – this configuration file controls SEO-friendly URLs and should all permalinks be set properly or you might encounter an Invalid JSON error. To check these, navigate to Settings Permalinks and ensure all the permalinks are set accordingly.
Next, it is crucial to investigate any issues with the REST API of your site. This could include incompatibilities between plugins or themes installed and its REST API; to do this use browser developer console and search for “The REST API encountered an unexpected response”.
If you encounter one of these errors, updating the plugin or theme may be necessary to keep your WordPress website operating efficiently. Though this may take some time and effort, the benefits are well worth your while when it comes to keeping things running smoothly.
If you still can’t resolve the Invalid JSON Error in WordPress, switching back to the classic editor (available as a plugin) might help. Doing this should eliminate Gutenberg block editor and may resolve the issue. Alternatively, if images uploading is causing issues for you then try doing so via FTP or another image uploader instead of uploading directly. If this doesn’t solve it then please reach out for assistance from plugin or theme developers as it could be their plugin or theme that needs fixing.
4. Check the plugins
Error 403 in WordPress can be extremely frustrating as it prevents you from editing your website. This error occurs when WordPress’s REST API cannot connect to your hosting server in order to update and store website data. Luckily, there are various troubleshooting steps available to resolve this issue, such as checking the.htaccess file, permalink settings, plugins or disabling Gutenberg for classic editor mode – whatever solution is chosen it’s essential that a backup of your site be created prior to making any modifications!
Error 503 can occur due to incorrect URL settings on your site. To rectify this situation, navigate to your WordPress dashboard and access “Settings – General,” making sure that “WordPress Address (URL)” matches with the domain name of your website so the REST API can connect with hosting server successfully.
Potential causes for this error include plugin conflicts. Since plugins can often cause errors in WordPress, it’s crucial that they’re tested individually to isolate which one(s) are responsible. To do this, visit your dashboard Plugins page and select them all; use bulk actions menu “Deactivate” option before returning back to website to reactivate them in order to see if Invalid JSON Error still appears after reboot.
If the Invalid JSON Error keeps appearing on your WordPress website, it may be wise to contact either a web developer or hosting provider in order to determine its source. Or use our WordPress Error Fixing Service which identifies and resolves more complex issues which might be the source.
The Invalid JSON Error is a common problem that affects WordPress websites, but don’t be alarmed if it happens when working on your site – there are ways to address it by following simple troubleshooting steps and quickly pinpointing its source.
