Error message when I tried to upload a picture in wordPress app for iPhone

There are a number of reasons why media uploads would fail in the app. Try following these steps to troubleshoot upload issues:

1. Check that your device has enough storage space available (we recommend at least 1GB of free space).
2. Try uploading your media using a different internet connection. If your network isn’t stable, this can cause media uploads to fail.
3. Contact your web host and check to see if they’re limiting incoming and outgoing connections over XML-RPC. The WordPress mobile apps use this file to communicate with your site, but some hosts limit connection requests to that file.
4. Confirm that you can upload the same image or video from your site’s wp-admin > Media section. If this also fails, you can verify your Maximum upload file size listed at the bottom of the Upload New Media page to confirm if this needs to be increased.
   
   To increase your upload file size, you’ll need to add code to your root .htaccess file or contact your host for assistance.
5. Check for any plugins that may be causing an issue. You can disable all plugins and try uploading media. If the issue doesn’t replicate, you can reactivate the plugins one at a time until the issue returns to narrow down the problematic plugins.
