So you got the dreaded Blog returned invalid data error? We’re going to need a bit more info to be able to help you.

Step 1: Launch the Settings app and go to WordPress settings


Step 2: Make sure you’re using 2.9 or a newer version, and enable Extra Debug.

Step 3: Go back to the WordPress app and do whatever you did before that caused the error

Step 4: Once you got the error, you need to plug your device to your computer and install a little tool called iExplorer (formerly iPhone Explorer). It’s free and available for Windows/Mac.

Find WordPress inside Apps, and then look for wordpress.log inside WordPress/Documents. That’s the file we need. But first…

Step 5: Open that file and take a look at it before sending it to us. We’ve done our best to avoid logging any personal data there. But since it’s recording whatever your blog is responding to the app, and it’s responding in an unexpected way, who knows? Just make sure you don’t send us any password or private information by mistake.

Or just go towards the end of the file and the error should be there. You might be able to figure out what’s wrong by yourself with just that.
