Error publishing remotely on Windows server (media uploads work)

  • I’m running into a weird error that I’ve never seen before. I can use the editor to insert an image or video when editing a post or page but when I preview/publish/update, I get errors like the following:

    Error
This page can't be displayed. Contact support for additional information.
The incident ID is: 752135680119-N/A.

    I’m not sure whether this error is coming from WordPress, PHP, IIS, or what. I used Microsoft’s Web Platform Installer to install on both my local and the production machines. I developed locally with no issues and used the All-in-One WP Migration to export the site to production.

    What I’ve noticed so far is that it works if i’m accessing the site locally on the production machine. I get the error specifically when I try to embed an image or an iframe (for video), even if the src url is referencing an image on another server. Text updates work fine. Images used within the theme or inserted through a custom field work fine. Saving some theme pages through the code editor will also trigger this error.

    I thought it might be a permissions issue but I’ve already tried allowing full control on the entire site for IUSR and IIS_IUSRS with no luck. I tried deactivating all plugins, switching to the default themes, and making a separate new WordPress install. Turning on WordPress and PHP debug logging didn’t seem to catch anything either.

    Hi @matikin9,

    Unfortunately the error doesn’t provide much insight into the actual issue – it’s a generic error message which IIS provides to limit data exposure.

    In the server logs there will be listed the actual error (generated by WordPress, PHP, or IIS itself) that can be used to debug your problem, most likely it’ll be accompanied by the 752135680119 error number.

    However, based on it happening only when you try to insert an embed or iframe, I have a feeling it may be a firewall or security module installed in IIS, blocking the request as it thinks it’s malicious.
