Nav Consistency Fix — July 12, 2026
Problem
Multiple ops portal pages had erratic behavior on mobile — hamburger menu didn't work, nav links were missing or stale, some pages showed no data.
Root Causes Found (3 issues)
1. Mixed nav strategies — inline vs fetched
Some pages had the nav hardcoded inline in the HTML, while others fetched /nav.html dynamically. The inline navs were stale — missing Audit, Costs, and Grafana links. The fetched navs were always up to date.
Fix: Every page should use:
<div id="nav"></div>
And fetch nav at the bottom of the page script:
fetch('/nav.html').then(r => r.text()).then(html => {
document.getElementById('nav').innerHTML = html;
if (typeof window.initNav === 'function') window.initNav();
});
Pages affected: backups.html, servers.html, services.html (all had inline navs that were replaced)
2. Ops.initNav() vs window.initNav() — TypeError kills nav
The initNav function is defined in utils.js as window.initNav, NOT as Ops.initNav. Pages calling Ops.initNav() throw a ReferenceError that kills ALL JavaScript execution on the page — including the data loading and rendering code.
Fix: Replace all Ops.initNav() with window.initNav():
// BROKEN:
Ops.initNav();
// FIXED:
if (typeof window.initNav === 'function') window.initNav();
Pages affected: index.html, backups.html, servers.html, services.html
3. CSS/JS MIME types — wrong content-type kills scripts
The backend (FastAPI FileResponse) and Caddy reverse proxy served JS and CSS files with Content-Type: application/json. Browsers refuse to execute scripts or apply stylesheets with the wrong MIME type.
Root causes:
- FastAPI's
FileResponse()without explicitmedia_typeparameter sometimes resolves.jsfiles asapplication/json - Caddy
handle_path /js/*block was nested inside anotherhandle_pathblock by accident (sed nesting bug) - File permissions were
600(root-only) — Caddy returned 403, browser silently failed
Fix — Caddy approach (most reliable):
ops.itpropartner.com {
handle_path /data/* {
root * /var/www/ops/data/
file_server
}
handle_path /js/* { # ← TOP LEVEL
root * /opt/ops-portal/static/js
file_server
}
handle_path /css/* { # ← TOP LEVEL
root * /opt/ops-portal/static/css
file_server
}
reverse_proxy 127.0.0.1:8090
}
Plus fix file permissions: chmod 644 /opt/ops-portal/static/js/*.js /opt/ops-portal/static/css/*.css
Verification:
curl -sI https://ops.itpropartner.com/js/app.js | grep -i content-type
# Expected: text/javascript; charset=utf-8
for page in / /services.html /servers.html /backups.html /audit.html /cost.html; do
echo "$page → $(curl -sS -o /dev/null -w '%{http_code}' https://ops.itpropartner.com$page)"
done
# All should return 200
Prevention Checklist
- Every new page: use
<div id="nav"></div>+ fetch pattern, never inline nav - Every new page: call
window.initNav()(notOps.initNav()) inside the fetch callback - After any Caddy config change: verify
handle_pathblocks are top-level, not nested - After adding any new static file:
chmod 644 - After any static file change: test with
curl -sIto verify MIME type
