SXA Error when open page in Experience Editor

Question

I am using Sitecore 9 with SXA 1.7. When I try to open page in Experience Editor, I got the below error. Any suggestions?

Error Rendering View: /Views/SxaLayout/SxaLayout.cshtml: Error while rendering view: '/Views/SxaLayout/SxaLayout.cshtml' (model: 'Sitecore.Mvc.Presentation.RenderingModel, Sitecore.Mvc').

Answer 1

From Error, It seems that there is some issue with the component you have added.

Remove all the component you have added using page design or change the page design to Default one. And if page loads for you in experience editor with Default page design then there must be some issue with you component configuration.

Your error is locating the Main placeholder. If you have used partial design for main container then remove that specific partial design and try to view the page.

It should work fine, if you haven't faced any issue during installation of SXA and site creation.

Answer 2

I have seen this happen when the Experience Editor cannot resolve the site correctly. Things to look for:

• Make sure that your Site Grouping has the correct URL in for both the CD and the CM urls. So maybe something like www.mysite.com|cms.mysite.com
• Make sure you are using the right url to edit the site if you have a multi-site setup

You can test this by going to the same page item in the Content Explorer, right click and go to the Experience Editor from that menu. If that works, it is the site resolving that is going wrong.

I have got this error when Parameters Template field on Controller Rendering had the wrong value(broken link).

It worth checking all renderings on your page. One of the renderings causes this issue. (because of something is broken on rendering itself). You need to isolate issue by figuring out, which rendering is broken. And then troubleshooting what is broken on that rendering is a much more simple task.
