Dashboard page is blank

Dashboard page is blank — content clipped by #wpbody having no height (one-line CSS fix)

Problem: Settings → Copy to Clipboard renders blank below the header. The stats cards, Recent Rules, Quick Actions and System Health are all cut off. Reproduces in Chrome/Edge, normal and incognito — so it’s not browser, cache, extension or network related.

Cause: The dashboard content actually renders fine — it’s clipped by CSS. The plugin emits an empty root and an absolutely-positioned, overflow:hidden panel:

<div id="ctc-dashboard-root"></div>
<div class="ctc-dashboard h-full ... absolute top-0 left-0 right-0 bottom-0 overflow-hidden">

Since the panel is absolute + top/bottom:0, its height resolves against the nearest positioned ancestor, #wpbody. WordPress sets #wpbody { position: relative; } but gives it no height (auto/content-driven). The absolutely-positioned panel contributes no height itself, so it collapses to ~75px — just the header row — and overflow:hidden clips everything below it.

#wpbody             height 75px  (auto, no explicit height)
  #ctc-dashboard-root  height 0px   ← collapse
    .ctc-dashboard     height 75px  ← clipped

Fix (verified working):

.settings_page_ctc #wpbody {
    height: calc(100vh - 32px); /* 32px = admin bar */
}

I tested this live — with that one rule all cards and sections render correctly.

Workaround for users: add the CSS above via a snippets/header-footer plugin until patched.
