Add Html.AntiForgeryToken in the _ShellLayout.cshtml file #140
Description
Hi,
We are using the Geta-optimizely-sitemaps plugin in our latest project, we started encountering multiple 500 errors from the navigation.bundle.js script on a site that uses Opti ID.
After some investigation, it appears that the _ShellLayout.cshtml file located at src/Geta.Optimizely.Sitemaps/Geta.Optimizely.Sitemaps.Views/Views/Shared/_ShellLayout.cshtml is missing a line. Specifically, there should be an @Html.AntiForgeryToken() line before the @Html.CreatePlatformNavigationMenu() line.
If you check this blog post: https://world.optimizely.com/blogs/matthew-slim/dates/2023/6/new-menu-system-released and read the comments, you’ll find a solution for this issue.
Example:
<body>
@Html.AntiForgeryToken()
@Html.CreatePlatformNavigationMenu()
<div @Html.ApplyPlatformNavigation()>
....rest of code
There’s also another blog post describing the same problem: https://world.optimizely.com/blogs/allthingsopti/dates/2025/10/a-day-in-the-life-of-an-optimizely-omvp---creating-a-blazor-add-on/
Best regards,
Anders
