  1. Go to your WordPress Website back-end with the link – Domain Name/wp-admin.
  2. Click on Settings & then Tools, there you will find, Site health tab
  3. This Site Health tab tells you the current Website issues going in your site whether they are related to Plugins, theme updates, old PHP versions, latest WordPress updates, or any other website loading issue.

Server error, certain DNS problems, WordPress Connectivity problem with the domain, old PHP versions, or restricted memory allocated to the site are all predicted to cause cURL error 28 on your websites.

  1. Check your website PHP version, upgrade if low.
  2. To find out where the exact problem is occurring, go to PHP INI manager and open the error display setting for the PHP version your site is running.
  3. Check your WordPress & it’s plugins update – Keep everything updated. Check your domain, IP, and DNS connections. Site – “What’s my DNS” is helpful – https://www.whatsmydns.net/.
  4. Increase PHP limits (check PHP INI for that) or Add a file “php.ini” in your Website’s root directory with the following code.
  5. Check the error log in cPanel to check which code line is causing the error in your website.
  6. Error logs also come up in File manager (outside public_html).
  7. If you are technically sound (highly recommended), then check your Server Security Configuration in mod_security, in WHM Panel. This is helpful if all your websites are showing the same error. However, if only 1 or 2 sites are showing this error, then the issue lies somewhere else.
  8. Contact your administrator or Hosting Provider.
  9. Try “Troubleshooting Plugin” of WordPress and deactivate all plugins through it. Then reactivate your plugins one by one to check which is causing the issue. (I would recommend to completely delete that plugin and then install it, a fresh).
