If for some reason the OpenFX plugin stopped working or displays the below error message in the OpenFX inspector: 

> No parameter is exposed to user or OFX Plugin is NOT available.

Please try to clear the OpenFX cache by doing the following:

   * Select *Go* > *Go to Folder...*
   * Type or paste in: \
     \&#xNAN;**`~/Library/Application Support/Blackmagic Design/DaVinci Resolve/`**
3. Delete the *OFXPluginCache.xml* file at this location
4. Relaunch Resolve

### Windows

2. Open OpenFX plugin cache file location
   * Open a *File Explorer* window
   * Go to \
     \&#xNAN;**`C:\ProgramData\Blackmagic Design\Davinci Resolve\Support\`**

### Re-enabling the OpenFX Plugin in DaVinci Resolve

When the OFX plugin causes a problem or crashes DaVinci Resolve it gets blacklisted and Resolve won't appempt to load it anymore. Even if you re-install a plugin or install a different version of the plugin.

In order to load the plugin again we need to tell Resolve to do so. Go to Preferences and Video Plugins section:

![Re-enable OpenFX Plugins](https://565437294-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MFqn5MuayPgQPMZ9pwf%2F-Mk7FuzfvbuERGApNrm-%2F-Mk7GN8tzE6MPHjTxcvk%2Fofx_reenable.png?alt=media\&token=71f6bc01-a5bb-4f92-8a1e-3ece53da3015)

Tick the checkbox next to the plugin, click **Save** and restart DaVinci Resolve. The plugin will be loaded on startup.
