I have a fresh installation of Sitecore 9.0.1 rev 171219 and am attempting to install SXA 1.6. I've downloaded the package and when attempting to install it, it fails with the following error in the logs:

ManagedPoolThread #7 09:11:03 INFO Installing item: items/master/sitecore/system/Modules/Layout Service/Rendering Contents Resolvers/SXA/Page List Contents Resolver/{93FC6E4C-9119-4C05-B8B5-41446A9BB5FA}/en/1/xml

ManagedPoolThread #7 09:11:03 ERROR Failed to save the item. Item ID: {FA86AD54-9CEC-4509-9EFD-DD6DBC608A5B}, database: master

I've searched all over and cannot find a way around this issue.

Has anyone encountered this before?

Any ideas on how I can get past this?

  • is it Solr up and running? Apr 4, 2018 at 15:00
  • Yes Solr is running properly. There were errors previously that required a dynamicfield entry; however, Solr is running without issue now. Apr 4, 2018 at 15:11

    @JamesEggers - Have you installed SPE (Powershell extensions) 4.7.2 before installing SXA? Apr 4, 2018 at 16:42
  • @PeterProchazka The error disappeared after installing SPE. Thanks!! Apr 4, 2018 at 17:27
  • Glad I could help @JamesEggers. Definitely misleading error message. Apr 4, 2018 at 17:33

1 Answer 1


This error could be caused by missing SPE module. Try to install Sitecore PowerShell Extensions 4.7.2 which is a prerequisite for SXA 1.6
