Server Mode → Settings → Display / Branding controls how the Panel looks to everyone who logs in — including your resellers and their clients.
Logo
Upload a PNG or SVG logo (recommended: SVG for sharpness at all sizes, or PNG at 200×50px minimum). The logo replaces the default Opterius wordmark in the Panel header.
Alternatively, provide a logo URL if the image is hosted externally. The Panel fetches and displays it directly from the URL — no upload needed. Use a stable URL; if the image moves, the logo breaks.
To revert to the default Opterius logo, clear the field and save.
Company Name
Sets the name that appears in:
- The browser tab title (
MyHost Panelinstead ofOpterius Panel). - Email notifications sent by the Panel.
- The suspension page shown to end users.
This does not affect URLs or any system-level configuration — it is purely a display label.
Brand Color
A hex color value applied to the primary UI accent (buttons, active nav items, focus rings). Keep contrast in mind — the Panel uses this color against both white and dark backgrounds in various components. Test readability after saving.
Custom CSS
A textarea for arbitrary CSS injected into the <head> of every Panel page via a <style> tag. Use this for minor overrides — adjusting font sizes, tweaking spacing, overriding a component color that the brand color picker does not expose.
/* Example: increase sidebar font size */
.sidebar-nav a {
font-size: 14px;
}
/* Example: custom header background */
.panel-header {
background-color: #1a1a2e;
}
Note: Custom CSS is applied after the Panel's own stylesheets. Specificity rules apply — you may need to match the selector specificity of the style you are overriding. If a change is not appearing, check specificity or add
!importantas a last resort.
Custom CSS is not sandboxed. Avoid using it to hide UI elements that control security-relevant features.
Suspension Page
When an account is suspended, visitors to that account's domains see a suspension page. You can customize this with:
- Custom HTML — replace the default "This account has been suspended" page with your own markup. Useful for including your support contact details.
- Redirect URL — redirect suspended accounts to a URL of your choice (e.g., your billing portal or a custom error page).
If neither is set, the default Opterius suspension page is shown (with your company name if set above).
White-Label Deployments
Branding settings here apply server-wide. For per-reseller branding (so each reseller's clients see that reseller's brand), see White-Label for Resellers.
