while trying to install SXA 1.7, i have run across the following error: One or more exceptions occurred while processing the subscribers to the 'item:saved' event.

I uploaded the package, then proceeded with the installation wizard, only to get that error. I've tried to re-install multiple times and i always get the same error. I tried doing an iisreset as some other websites suggested that but it didn't help.

Here is a part of the errors log:

  • Would be helpful if you would attach everything that's in the log files (whole exception details). – Dawid Rutkowski May 10 '18 at 15:30
  • @DawidRutkowski I'm not sure which part to add exactly, but i edited the question and have included the exceptions including "item:saved" – Mie ElMansy May 10 '18 at 15:47
  • @DawidRutkowski I reinstalled PS Extensions then tried to reinstall the SXA 1.7 package and it worked.. thank you for your help :) – Mie ElMansy May 10 '18 at 16:16

I suspected i had some corrupted file from the initial powershell extensions installation, so I reinstalled the "Sitecore PowerShell Extensions-4.7.2" package first, then reinstalled the "Sitecore Experience Accelerator 1.7" package, and it worked.
