Problem creating new section - Busy saving the configuration. The section has not been saved. Try again later.

Creatio 8.1.2, clean database (MS SQL), starting from scratch.

These are the exact steps i took:

• Restored Database from Creatio Zip
• Configured IIS
• In system settings, set the "prefix for object name" to "Wlf"
• Go into Application Hub, create new application
• In system settings, set the "current package" to the one that was created in previous step
• In new application, click Navigation and Sections, then "New Freedom UI Section"
• Set title of new section, click "create"
• The following error is displayed:

• 

   

  Any thoughts? The below is what i see in error log:
