Notice: file\_get\_contents(): read of 8192 bytes failed with errno=21 Is a directory in /Applications/Net:Web/RapidWeaver 8.app/Contents/Resources/RWWebServerLaunch.php on line 178

The above message appeared when previewing a blog page that had been previously updating successfully. I also preview in Safari and the same message appears.

The edit page looks fine. Obviously I haven’t uploaded again.

I am using RapidWeaver 8, and the Poster plugin.

Thanks - Nigel

You said blog page, but you also mentioned “poster plugin”. So to make sure we understand what is giving you problems, so are you are on a stacks page using poster stacks or the built in blog plugin?

My guess is that it’s a stacks page using @instacks poster? If so what version?  
The error looks to be a PHP error message. What exact version of RapidWeaver (eg. 8.9.3)? What version of macOS are you using?

It’s either a RW or Stacks plugin PHP server preview bug, not related to Poster Stack. Will not occur on the published website.

Thanks both. It was one of those strange ones where, after I opened and closed Rapid Weaver a few times, the problem went away. Thanks for the replies anyway, and I much appreciate it. Best wishes - Nigel
