Can't Same Home Page Edits

Hi Tim,   I can save the page settings, and edit all of the pages,  Except the Homepage.   
when I try to save the homepage in the Design editor, it just spins. I'm using sytist 5.4.3 

Is this a modsec error? (I ask because the page designer still works on all the other pages!)

I've tried to OK it through cloudflare (not a cloudflare expert)

I'm looking for file persmissions, but not seeing anything that looks out of place...

I can't type today...  can't saVe design edits...  

Doesn't have anything to do with file permissions. You will need to get with your host and let them know you are triggering mod security when saving.

Thanks Tim,  Yep ...  in this case it was a waf rule through Cloudflare.  Now there's a learning curve! lol
