Support » Plugin: Wordfence Security - Firewall & Malware Scan » WordFence Seems To Be Blocking My Theme Customiser

  • Resolved Jae


    When I go to Appearance > Customize it comes up saying

    This page isn’t working
    [] is currently unable to handle this request.

    (Replace [] for the actually website address, which I cannot post here for security reasons and client confidentiality.

    When I disable WordFence it works fine. But when I activate it, I get the above error.
    I’ve tried whitelisting the wp-admin/customize.php, but it won’t let me unless I enter something in the Param field, which I’m not sure what to enter.

    I tried copying and pasting into the Param field all that appears after the ? after the URL. But that didn’t make any difference.

    I’ve had to disable the plugin while I’m working in the Theme Customizer, which I don’t like doing, as I know I’m opening the site up to attack.

    Please advise how I can rectify the issue and/or what I need to put in each of the field in the Whitelist URL section, if that’s the issue – or else, what is the issue?

    Many thanks,

  • Hi Jae,

    The error you’re describing seems to be a 500 error being thrown by the server indicating it doesn’t have enough resources available to handle processing all the requests being made of the system when you are visiting Appearance > Customize.

    When you have the firewall enabled, are you seeing the same error for any other paths? This could be indicative of a more system-wide need for resources, rather than a particular need for a given path/plugin. If you have access to your server logs, or if your hosting offers support, you may want to check those logs as well to see if there’s any indication that you’re running out of resources and where. If the error is occurring anywhere else in your site, it could show up in the logs and give you a clearer idea of what may be causing the overload.

    Hi @@linseyja

    Since we haven’t heard from you for a while I’m going to go ahead and resolve this thread. If you have any other questions or concerns, don’t hesitate to open a new one.
