SharePoint Online–Enabling Custom Script

When Creating an Office 365 SharePoint site, you might want to turn on custom Scripting.

Steps here: https://support.office.microsoft.com/en-us/article/Turn-scripting-capabilities-on-or-off-1f2c515f-5d7e-448a-9fd7-835da935584f?CorrelationId=365c212d-8b7e-45b9-b285-84416dd95952&ui=en-US&rs=en-US&ad=US

With Custom Scripts turned off you might experience some weird behavior like:

• Content Types and Site Columns Galleries are not showing up in the Site Actions menu.
• When Mapping a SharePoint Library to a local drive, you might get Access denied errors when trying to upload files.
• CEWP and Script editor web part might be missing from the Web parts list when editing a page.
