# Troubleshooting Favvy

> Troubleshooting guide for Favvy with common setup and export issues.

### Your selected layer must be a square

Favvy will let you know if you've selected a layer that isn't square; this can be resolved by resizing your frame
    until the width and height are identical (eg. **512x512**).

  ### Blank file extensions using Figma desktop app on Windows

There's a known issue with the Figma desktop app (only on Windows), which also happens for normal file exports from
    Figma. When you go to save your file, you may see an "all files" label. If you ignore this and continue by clicking
    "Save", it should still save the file with the correct extension and allow you to open it as expected after it has
    downloaded to your computer. If it still saves the file with a blank extension, you should be able to rename the
    file to manually append the correct extension to the file name.

  ### VPN may be required in China

Please note, if you're in China, the accounts server _may_ be blocked by "The Great Firewall of China". If you're
    seeing an activation error, despite using a valid key, you will likely need to use a
    [VPN](https://protonvpn.com/free-vpn/) to resolve the issue.

  ### 'An error occurred while loading the plugin environment'

This may happen in the Figma desktop app if [the Use Developer VM](https://www.figma.com/plugin-docs/debugging/#developer-vm) debug setting in Figma is enabled by mistake; you can make sure it's turned off by **right-clicking** anywhere on your Figma canvas, hovering over **Plugins**, then hovering over **Development**, and making sure that the **Use Developer VM** is _unchecked_; after it is unchecked (and does _not_ have a tick icon next to it), re-running the Figma plugin should work as expected.
