Troubleshooting SeedProd's 'Page Not Found' Error When Saving Changes

31 threads Sep 10, 2025

Many users of the 'Website Builder by SeedProd' plugin encounter a frustrating 'Page Not Found' error immediately after clicking the 'Save all changes' button. This issue prevents updates to Coming Soon or Maintenance Mode pages from being stored. Based on community reports and solutions, this article explains why this happens and provides the most effective troubleshooting steps.

Why Does This 'Page Not Found' Error Occur?

This error is typically not a bug in the SeedProd plugin itself but is instead caused by an external security measure. The two most common triggers are:

  1. Overzealous Security Plugins or Firewalls: Plugins like WordFence or server-level firewalls can sometimes misinterpret the data being saved by SeedProd's page builder as a malicious code injection attempt. This causes the security system to block the save request, resulting in a 'Page Not Found' or similar error message.
  2. Host-Level Security Rules: Some web hosting providers have strict mod_security or other firewall rules active on their servers. These rules can also block POST requests that contain certain HTML or script content, preventing the page from saving.

How to Resolve the Saving Error

Try the following solutions, starting with the most common fix.

Solution 1: Check Security Plugins and Firewalls

If you are using a security plugin, this is the most likely culprit.

  • Temporarily disable any security or firewall plugins (e.g., WordFence, Sucuri, iThemes Security) and try saving your SeedProd page again. If it works, you know the conflict is there.
  • Re-enable the plugin and put it into "Learning Mode" or its equivalent. Then, go back to SeedProd and save your page. This often teaches the firewall that the action is safe and allows it to proceed in the future.

Solution 2: Test for a Theme or Plugin Conflict

While less common than a firewall issue, a conflict with another plugin can cause problems.

  • Temporarily switch your WordPress theme to a default theme like Twenty Twenty-Four.
  • Deactivate all other plugins except for SeedProd.
  • Try to save your page. If it works, reactivate your plugins one by one, testing after each, to identify which one is causing the conflict.

Solution 3: Contact Your Web Host

If the above steps do not work, the issue may be at the server level.

  • Contact your hosting provider's support team.
  • Explain that you are unable to save changes in the SeedProd page builder and receive a 'Page Not Found' error.
  • Ask them to check their error logs for any blocked POST requests to /wp-admin/admin-ajax.php or /wp-admin/options.php and to whitelist any necessary actions for the SeedProd plugin.

Solution 4: Directly Save Settings (Advanced)

As a temporary diagnostic step, you can try saving your WordPress settings directly. Navigate to YOURSITE.com/wp-admin/options.php in your browser, scroll to the very bottom of the page, and click 'Save Changes'. If this also generates an error, it strongly indicates a server-level or security plugin conflict that is affecting core WordPress functions.

Important Note on Caching

If your page appears to save but the changes are not visible on the front end, remember to clear all caching layers. This includes your browser cache, any caching plugins you have installed (e.g., WP Rocket, W3 Total Cache), and your hosting provider's server-side cache (if applicable).

By methodically working through these steps, most users are able to identify and resolve the conflict that is preventing them from saving their SeedProd pages successfully.
