Error When Saving Theme Options

If you encounter an error when saving Theme Options, you may be experiencing a Server Error 500, Server Error 404, Server Error 403, or a blank page.

Below is a compilation of common causes identified over time.

Typically, these issues relate to hosting resources that interrupt the option-saving process.

Please note that Uncode is a rigorously tested and trusted product. If a core function like the Theme Options fails to operate specifically within your installation, the issue is likely rooted in server-side settings.

We recommend contacting your hosting support team to investigate the server error. Request that they verify the specific error details found in the Error Log file.

Error When Saving Theme Options – Memory Limit

If an error occurs while saving Theme Options, please verify that there are no warnings regarding Memory Limit within your System Status. The WP Memory Limit defines the maximum amount of RAM your site can utilize simultaneously.

Memory limit issues typically arise when the server environment does not meet the requirements for a modern WordPress configuration.

Extra Plugins

If you encounter an error, attempt to deactivate all third-party plugins to determine if this resolves the issue. Conflicts or performance bottlenecks caused by external plugins are a common cause.

PHP Version

Errors may also stem from an outdated PHP version. Ensure your host provides the latest stable version recommended by WordPress, such as PHP 7.4 or higher.

Limited Resources

Certain hosting providers impose strict resource limits. Saving Theme Options triggers multiple simultaneous actions that may be blocked by these restrictions. Please request that your host review these specific settings.

Below is an example response from a cooperative hosting provider regarding this issue:

Yes, it seems that you triggered one of our security measures called Mod Security. It appears that the delete function is causing multiple backend calls simultaneously, which is causing the system to malfunction. However, we have disabled this rule since it only applies to the admin area, so there should be no increase in the risk of any account exploits.

Pattern Match (ModSecurity)

Users have reported instances where the saving process was blocked by a server-side pattern match:

Request: POST /wp-admin/options.php  Action Description: Access denied with code 403 (phase 2).  Justification: Pattern match "(?i)([s"'`;/0-9=x0Bx09x0Cx3Bx2Cx28x3B]+onw+[sx0Bx09x0Cx3Bx2Cx28x3B]*?=)" at ARGS:_uncode_post_custom_fields_settings_array.

A common solution involves navigating to: cPanel → ModSecurity → Deactivate

Addressing these potential issues helps ensure the Theme Options save correctly and maintains optimal website performance. For further assistance, please refer to our support documentation or contact our support team.
