My WordPress site uses the TubePress plugin to display thumbnails of training videos. And it works great.
I am using the SmallBiz theme.
The site comes up OK and the videos all look and work great, but when TubePress is activated, a 500 error is generated when I test the site at GTMetrix.com. Also, Google Webmaster Tools cannot FETCH and when TubePress is activated.
When I deactivate TubePress, these two problems go away. But, of course, so do all my videos!
Any thoughts on this? Might there be a work-around or fix to this?
