Landing Pages not Saving (v.2.13.1)

I am using a hosted service and installed my mautic app through Softaculous. However; when I go to create a landing page or email, it does not save it. It will act as if it is saving, but then the Build/Save&Close/Apply buttons will disappear.

@Charles Robinson What mautic version you have installed ?

What is your hosting ?

Try to clear cache and update the database schema.
