[Resolved] IPB Converter Path Issue

Did you try setting up the path starting by the xenforo path then go backwards until you find the one.
For example
1- [xenforo root]/data/avatar/l/0
2-[ftpuser]/[xenforo root]/data/avatar/l/0

---

or try going into Appearance -> Style Properties -> General -> Path to Images in Xenforo the admin panel and clicking "reset" and "save". It will change the image path back to the general path.
