Thanks for contacting us.
Typically when we’ve seen this error it’s because TubePress is “the straw that broke the camel’s back” and pushed the site over the memory limit. If you can’t reduce memory usage by removing any unnecessary code from your site, then we would recommend that you try TubePress Express, which is our cloud-hosted TubePress installation that requires no installation and takes the load off your site entirely. We offer a free 30-day trial of TubePress Express, and of course if you decide to switch we’ll be happy to refund your purchase of TubePress Pro.
