On WHMCS order form templates, the {block name="head"} you added is not guaranteed to be honored in that context. These templates already include a dedicated file for head assets:

{include file="orderforms/{$carttpl}/includes/head.tpl" pageTitle=$LANG.revieweroder}


So the safe, WHMCS-native way is to put your <link> in that includes/head.tpl and let the engine place it in the <head>.

Do this (2 minutes)

Remove any <link rel="stylesheet"...> lines you added at the top of:

/templates/orderforms/ibrandbiz_comparison/products.tpl
/templates/orderforms/ibrandbiz_comparison/configureproduct.tpl
/templates/orderforms/ibrandbiz_comparison/viewcart.tpl


Create this file (if it doesn’t exist yet):

/public_html/portal/templates/orderforms/ibrandbiz_comparison/includes/head.tpl


Put exactly this in it (no extra dots/newlines):

{* IBrandBiz order form head assets *}
<link rel="stylesheet" href="{$systemurl}templates/orderforms/{$carttpl}/style.css?v={$assetVersion}">


Make sure your real CSS is in:

/public_html/portal/templates/orderforms/ibrandbiz_comparison/style.css


(not just in /css/style.css; the root style.css should contain the full styles)

WHMCS → Utilities → System Cleanup → Empty Template Cache

Hard refresh /index.php?rp=/store/web-hosting (Ctrl/Cmd+Shift+R)

Quick verification

View page source and search for ibrandbiz_comparison/style.css — it should be inside <head>.

Open the link you see in source; it should resolve to:

https://portal.ibrandbiz.com/templates/orderforms/ibrandbiz_comparison/style.css?v=...


and return 200 (you’ve already confirmed the file itself loads 👍).

Why the previous attempt didn’t stick

The {block name="head"} isn’t used by these orderform templates, so the link wasn’t making it into <head>.

Also, in one screenshot the <link> broke across lines around /style .css, which can create odd parsing in some cases. Moving it to includes/head.tpl avoids that entirely.

Once this is in place you should see your green, rounded IBrandBiz layout on the store page.
