Just wanted to check if there's anyone here already encountered the error traces below when opening the Sitecore Experience Editor.

I tried the workaround of reverting to SHEER UI, but I didn't do the trick. Described here: https://community.sitecore.net/developers/f/5/t/3049

Answer 1

Actually, after enabling the necessary configuration related to Content Testing \Website\App_Config\Include\ContentTesting, the said error didn't appear anymore

In my case:

• Sitecore.ContentTesting.ApplicationDependencies.config
• Sitecore.ContentTesting.config
• Sitecore.ContentTesting.Intelligence.config
• Sitecore.ContentTesting.Mvc.config
• Sitecore.ContentTesting.Processing.Aggregation.config
• Sitecore.ContentTesting.Solr.IndexConfiguration.config

Answer 2

The info in the link referenced in the question only spoke about updating the Sitecore.ExperienceEditor.config. However, this This KB Page also lists the Sitecore.MvcExperienceEditor.config to be edited. Editing both configs worked for me.

Answer 3

After trying a number of these solutions our issue was that the SPEAK URLs require a particular case be used in the request.

If you're using URL Rewrite 2.x to lowercase URLs for SEO purposes, you'll need to manually add an exclusion for /-/speak/ requests.

<rule name="LowerCaseRule" stopProcessing="true">
    <match url="[A-Z]" ignoreCase="false" />
    <conditions>
        <add input="{URL}" pattern="^/sitecore" negate="true" />
        <add input="{URL}" pattern="^/temp" negate="true" />
        <add input="{URL}" pattern="^/ScriptResource" negate="true" />
        <add input="{URL}" pattern="^/WebResource" negate="true" />
        <add input="{URL}" pattern="^/Shibboleth.sso" negate="true" />
        <add input="{URL}" pattern="\.axd" negate="true" />
        <add input="{URL}" pattern="\.asmx" negate="true" />
        <add input="{URL}" pattern="\.svc" negate="true" />
        <add input="{URL}" pattern="^/layouts/system" negate="true" />
        <add input="{HTTP_URL}" pattern="\?.*sc_mode" negate="true" />
        <add input="{URL}" pattern="\/-\/speak" negate="true" /><!-- SPEAK addition -->
    </conditions>
    <action type="Redirect" url="{ToLower:{URL}}" />
</rule>
