StatusYour installation is up to date.
Note: This page shows some information that is helpful during setup and upgrades but for security it would be best not to show any information when the system is up to date. You can disable setup and suppress all information on this page by setting DisableSetup=true in Web.config. When you need to upgrade, you can set this back to false. If you are logged in as Administrator setup will run and you will be able to see this page even if it is disabled in Web.config so you can easily leave it disabled and just login before upgrading. But if you are not logged in you will need to enable setup in Web.config.

Hello 

Yes, it is there. And was before (i didn't change my user.config).

Anyway, i did as your recommendation (change web.config).

But it keeps going to english site (site id 1), no matter if i put /br/ or put /es/.

:(

This is the settings i have in user.config, about multisite:

<!-- ******* multi site installation settings -->
<add key="AllowMultipleSites" value="true" />
<add key="AllowDeletingChildSites" value="false" />   
<!--      
    UseRelatedSiteMode means all sites in a multi site installation use the same users
        all users must have a site id so in this mode we use the same site id for all users
-->    
<add key="UseRelatedSiteMode" value="true" />
<add key="RelatedSiteID" value="1" />
<add key="RelatedSiteModeHideRoleManagerInChildSites" value="true" />
<add key="AllowFileManagerInChildSites" value="false" />
<add key="AllowPasswordFormatChangeInChildSites" value="false" />
<add key="ShowSystemInformationInChildSiteAdminMenu" value="true" />
<add key="UseFoldersInsteadOfHostnamesForMultipleSites" value="true" />
<add key="DisallowedVirtualFolderNames" value="Admin;ClientScript;Controls;Data;FCKeditor;Modules;NeatHtml;NeatUpload;Secure;Services;Setup;SiteOffice;WebStore" />
<add key="EnableSSLInChildSites" value="false" />
<!--   
    if you want to have different smtp settings per site, set EnableSiteSettingsSmtpSettings to true
    and smtp settings will appear in SiteSettings. otherwise use the smtp settings below
-->
<add key="EnableSiteSettingsSmtpSettings" value="true" />
<add key="MaskSmtpPasswordInSiteSettings" value="true" />
<add key="ShowSmtpEncodingOption" value="false" />    
<!-- ******* end multi site installation settings -->

Thanks a lot, Joe A/D. 100%

(I think this can be a solution for this topic too, am i right? >> topic = https://www.mojoportal.com/Forums/Thread.aspx?pageid=5&t=12033~1

I added this to user.config, and website is running great now.

<add key="UseTransferRequestForUrlReWriting" value="false"/>

About version (my last was 2.3.8.6)...

... because in the (very) past, i had a lot of problems when updating.

So, i postponed it as i could. My website have more than 1.000 visitors worldwide per day, so any small problem could became a big problem.

This Sunday, i decide it was time to be updated, i read a lot in the morning. Because i would like to add Facebook comments, Related Content (now possible in Blogs) and other enhanced stuff. 

After reading, i found that upgrading is very simple, you just have to follow guidelines.

The only part i missed in my readings, was this above tip.

Now that i know that it is simple, i will update more times. 

This is the steps i followed:

1) 
log as Admin
