Hello,
I've recently attempted to use Bridgy with my [WordPress website](http…s://willtmonroe.com) to post to [Twitter](https://twitter.com/willtmonroe). My procedure is pretty simple, I write a short post (see below) and select the option to `Syndicate to Twitter via Bridgy`. A few days ago, this succeeded but since then I've just had a series of errors.
The post can be found here: https://willtmonroe.com/uncategorized/104/
The error I can see on Brid.gy is below.
```

Do you have any advice on how I could troubleshoot this?
