So I am trying to update the theme on the SharePoint site to Green. Company colors pretty close. Anyway, the code runs flawlessly. But borks the site badly.

I can get it back to what I need but I need this code to work. I have around 500 SharePoint sites to update and well this is just failing.

URL changed to protect the innocent (ME)

What it looks like after the elephant borkings. Rod: Borked SharePoint site? Anyone?[^]

Code Example.
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client")
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client.Runtime")
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client.SharePointOnlineCredentials")

$tempC = new-object System.Net.WebClient
$tempC.UseDefaultCredentials=$true
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext("http://bergren.net/")
$Ctx.Credentials=$tempC.Credentials

#Get the Web
$Web = $Ctx.web
$Ctx.Load($Web)
$Ctx.ExecuteQuery()

#Frame Master page URL
$MasterPageURL = "$($web.ServerRelativeUrl)/_catalogs/masterpage/seattle.master"

#Set Default Master page & Custom Master page
$web.CustomMasterUrl = $MasterPageURL
$Web.MasterUrl = $MasterPageURL
$web.Update()
$Ctx.ExecuteQuery()

$fontSchemeUrl = "$($web.ServerRelativeUrl)/_catalogs/theme/15/fontscheme003.spfont"
$themeurl = "$($web.ServerRelativeUrl)/_catalogs/theme/15/Palette013.spcolor"
$imageUrl = "$($web.ServerRelativeUrl)/_layouts/15/images/siteIcon.png?rev=23"

$web.ApplyTheme($themeurl, $fontSchemeUrl, $imageUrl, $false)
$web.Update()
$Ctx.ExecuteQuery()

What I have tried:

I have messed with the code alot. I have also tried Server side code on the SharePoint servers that pretty much do the same thing. Everything ends up looking like this.
