Missing Blank Site Template in SharePoint 2013

When settings up site collectons, many use the Blank Site Template.
But in SharePoint 2013 no Blank Site Template.

Solution:

Run the command Get-SPWebTemplate to get the full list of the available templates.
Blank Site template ID is STS#1.

Go to folder C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\TEMPLATE\1033\XML ,and open the WEBTEMP.XML file. There, you'll find a link like this.

Just change the Hiden="TRUE" to Hiden="FALSE"

Next time you want to create a new site, you'll get the Blank Site Template.

This is for English Language pack, for other Language choose diferent folder of  "1033"  C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\TEMPLATE\1033\XML
E.g. For Serbian (Latin) Language pack is "2074".

Enable workspace field in an existing SharePoint 2013 calendar

Meeting workspaces, site templates designed specially for meetings, are a discontinued feature in SharePoint 2013.
In SharePoint 2013 the meeting workspace templates are still available, but hidden.
But what if you want to use meeting workspaces on an existing calendar created from the SharePoint 2013 standard calendar template or a calendar that has been migrated from SharePoint 2010. It’s quite easy using the SharePoint Management Shell.


Replace URL and the name of your calendar.

$web = Get-SPWeb http://portal
$list = $web.Lists["Calendar"]
$myAss = [Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint");
$type = $myAss.GetType("Microsoft.SharePoint.SPField");
[System.Reflection.BindingFlags]$flags = [System.Reflection.BindingFlags]::Instance -bor [System.Reflection.BindingFlags]::NonPublic
$SetFieldBoolValue = $type.GetMethod("SetFieldBoolValue",$flags)
$field = $list.Fields.GetFieldByInternalName("WorkspaceLink")
$arr = @()
$arr+="Sealed"
$arr+=$false
$SetFieldBoolValue.Invoke($field, $arr);
$arr = @()
$arr+="Hidden"
$arr+=$false
$SetFieldBoolValue.Invoke($field, $arr);
$method = $type.GetMethod("UpdateCore", $flags);
$method.Invoke($field, $true);
$field.ShowInEditForm = $true
$field.ShowInViewForms = $true
$field.Update()
