XenForo Add-on Debug Tip – xenbros/Auto Threadthumbnail​

Error:​

You must log in to view
(2 lines)

File to Edit:​

You must log in to view
(1 lines)

Method:

You must log in to view
(1 lines)

Cause:​

The method tries to manually build a full base URL using:

You must log in to view
(1 lines)

However, the XF\Http\Request class does not have a getUri() method, causing a fatal error.

---

Incorrect Code (Do NOT use):​

You must log in to view
(4 lines)

Correct Code (Use This Instead):​

You must log in to view
(3 lines)

---

Fix Instructions:​

1. Open the file:

You must log in to view
(1 lines)

2. Find the method:
getfirstPostImgUrl()
3. Replace the block that uses getUri() with the corrected version above.
4. Save and recompile templates if needed.

---

Bonus Tip:​

• 'attachments' → returns a relative URL: /attachments/xyz.jpg
• 'canonical:attachments' → returns a full URL: https://example.com/attachments/xyz.jpg

Use canonical: when generating image URLs for email templates, OG/meta previews, or anywhere a full URL is required.

Hope this helps you avoid the same issue!
