I am a first time user of gantry4 and it is driving me crazy!!!
The default home page includes a latest news post. It allows me to remove some text. But when I type in new text with photo only the photo shows up.? what am I doing wrong.
I am using mamp...On some instolations it will display the date correctly and on the next instolation it displays the default date two times?
There are 2 base concepts here: Default Settings and Overrides.
These concepts are applied to 2 main areas: Theme Settings and Widgets.
Default Settings are what you want on EVERY page. Want your Menu Widget on every page? Configure it under Widgets > Default Settings. Want a specific Accent Color on every page? Configure it under Theme Settings > Default Settings
Want something on only one page, or maybe just a couple pages? Use an Override...
Overrides are used when you want to add/remove a Widget on a specific page(s) or you want to change a Theme Setting for a specific page(s). Overrides use the Assignments Tab in the Theme Settings for that Override to control what page/post/menu item/type that Override gets applied to. Make sure you're not applying multiple Overrides to a single page.
As to your specific issue... I'm not sure I follow... here's a vid on setting up a blog in G4 that might help:
Can't really help troubleshoot MAMP issues either unfortunately... if you have the site live and something seems bugged we can take a peak... but generally server administration is outside of our scope here
