More info.
It’s allowing me to modify and update elements such as chunks and snippets, but no resources or pages. The resource menus are gone. Nothing had changed, just been working along on this web site, updating records. WTF . . .
<facepalm>
Problem solved. I was led to the solution by this thread

Though it is not a browser cache issue. We are in the final stages of finishing up a site, applying SEO rules and I was instructed to redirect index.php to /. This rewrite rule, inserted after old URL rewrites and before the !-d and !f directive,
#RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/]+/)*index\.php\ HTTP/
#RewriteRule ^(([^/]+/)*)index\.php$
http://www.example.com/$1 [R=301,L]
Which redirects any directories request for index.php to it’s parent directory (Yeah, <facepalm X10> )
Apparently this fuggered up the admin context. Odd though that it was **just** the resources that were all affected and I could still modify elements.
Obviously . . . change the rule so it only redirects at root.
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/]+/)*index\.php\ HTTP/
RewriteRule ^index\.php$
http://www.example.com/$1 [R=301,L]
