  • The script is incorrect beside a syntax error on line 19
    The $MasterPageURL is built up by de web url this must be the site collection url
    otherwise the url is wrong with a site collection having one or more subsites (webs)
    and then the $MasterPageURL can be set before the loop as it wont change anymore for all the sub sites (webs)
    If you run the above script subsite wont open and will give a file not found (because of the incorrect master url).

    • Well, that depends on how you have deployed the master page! Ideally, it should be deployed at each web – while its possible to inherit from the site collection.
