In ArcGIS Enterprise 10.7, creating more than 39 pages within a site through ArcGIS Enterprise Portal causes "An Unexpected Error has Occurred" page. There is documentation stating there is no limit to the number of pages that can be made, therefore users should be able to create more than 39 pages without any error. Below is documentation on creating pages for a site: https://enterprise.arcgis.com/en/portal/latest/use/creating-pages-on-your-site.htm
