Troubleshooting Common 'Under Construction' Plugin Saving Issues

13 threads Sep 16, 2025 Plugin → Under construction

Content

Users of the 'Under Construction' plugin occasionally report issues where their settings or design changes fail to save properly. This can manifest as checkboxes resetting, a failure to update the live page, or even triggering a 500 Internal Server Error. Based on community reports, here are the most common causes and their solutions.

Common Symptoms

  • Whitelisted user role selections do not stick after saving.
  • The live site does not update to reflect changes made in the plugin's preview.
  • Saving changes results in an HTTP 500 error or redirects to a 404 page.
  • An error message appears: Error: Options page ucp_options not found in the allowed options list.
  • Specific HTML formatting (like the <sup> tag) is stripped out upon saving.

Why This Happens

These problems are typically not caused by a single bug but can arise from a few different sources:

  1. Caching: Heavy caching at the server, plugin, or browser level can prevent recent changes from being displayed.
  2. Conflicts: A temporary conflict with another plugin or the theme can interfere with the plugin's ability to save options to the database.
  3. Corrupted Installation: Sometimes, the initial plugin installation or update process can become corrupted, leading to unexpected behavior.

How to Fix It

1. Clear All Caches

This is the most common fix. If your changes appear correctly in the plugin's preview but not on the live site, caching is almost always the culprit.

  • Clear your WordPress caching plugin's cache (e.g., WP Rocket, W3 Total Cache).
  • Clear any server-level cache (e.g., Varnish, NGINX). Contact your hosting provider if you're unsure how to do this.
  • Clear your browser cache and cookies, or test the site in a browser's incognito/private mode.

2. Perform a Conflict Test

If you are getting errors when trying to save (like a 500 error), a plugin or theme conflict is likely.

  1. Temporarily deactivate all other plugins except 'Under Construction'.
  2. Try to save your settings again. If it works, reactivate your plugins one-by-one to identify the one causing the conflict.
  3. If the problem persists with all plugins off, temporarily switch to a default WordPress theme (like Twenty Twenty-One) and test again.

3. Reinstall the Plugin

For errors like Options page ucp_options not found, a fresh installation can often resolve the issue.

  1. In your WordPress dashboard, go to Plugins → Installed Plugins.
  2. Deactivate and then delete the 'Under Construction' plugin. Note: This will not delete your saved settings.
  3. Install and activate the plugin again from the WordPress repository.
  4. Check if you can now save your settings.

4. Check for Known Formatting Limitations

The plugin's content editor may strip out certain HTML tags. For example, the <sup> tag for superscript is known to be removed upon saving. This would require a code modification to fix and is best handled by the plugin's developers in a future update.

When All Else Fails

If you continue to experience issues after trying these steps, the problem may be more complex and require deeper investigation. The 'Under Construction' team has requested site URLs in the past to investigate specific server configurations or errors. You can search the WordPress support forums for your specific error message to see if other users have found a solution.
