Help! I’m stuck with a post update problem in WordPress.
I keep getting this error when I try to update my posts:
Updating Failed. Invalid JSON body passed.
I’ve already tried:
- Changing permalinks
- Turning off plugins one by one
But nothing seems to fix it. I’m using WordPress 5.5.1 with the Newspaper theme (version 10.3.6.1).
I thought it might be the Ultimate Blocks plugin causing trouble with Gutenberg, so I turned that off too. No luck there either.
Has anyone run into this before? Any ideas on what else I could try to get my posts updating again? It’s really frustrating not being able to make changes to my content.
I ran into this exact problem a few months back. What finally fixed it for me was disabling my security plugin (I was using Wordfence at the time). Turns out it was interfering with the post update process somehow.
After disabling the security plugin, I was able to update posts again. Then I gradually re-enabled features until I isolated the specific setting causing the issue.
If you’re using a security plugin, try temporarily deactivating it to see if that resolves things. Just remember to re-enable it once you’ve sorted out the problem.
Another thing to check - make sure your WordPress installation and all plugins/themes are fully up-to-date. Outdated components can sometimes cause weird conflicts like this.
Hope this helps! Let us know if you get it working.
hey man, i had this problem too. turns out my host had weird php settings. i contacted support and they fixed it. maybe give that a shot? also, have u tried updating wordpress to the latest version? good luck!
I’ve encountered this issue before, and it can be quite frustrating. In my experience, it’s often related to server configuration or caching problems. Have you tried clearing your browser cache and WordPress cache? Sometimes, that simple step can resolve the issue.
If that doesn’t work, I’d suggest checking your server’s PHP memory limit. You might need to increase it if it’s set too low. Contact your hosting provider to adjust this setting if necessary.
Another potential fix is to manually update your WordPress core files. Download a fresh copy of WordPress 5.5.1 and replace the wp-admin and wp-includes folders via FTP. This can sometimes resolve conflicts causing the JSON error.
If none of these solutions work, consider temporarily switching to a default WordPress theme to rule out theme-related issues. Good luck troubleshooting!
