is there anyway to wipe everything from plugin inc the db if there is anything in there and start fresh and test again?
You can delete all the db rows in the wp_options table related to TubePress with the following MySQL query:
delete from wp_options where option_name like 'tubepress-%';
Of course, I strongly suggest backing up your database beforehand, just in case. And obviously you'll want to change "wp_options" to whatever your WordPress options table is called (as you might have a non-default tables prefix).
I am the hosting provider Eric, its running on my server.
Nothing interesting in the PHP error log? Or nginx logs? A quick and dirty test would be to put in an echo statement at the top of this file, then re-try this URL to see that something is printed out. That will at least let us know that the server is responding normally. Very odd that nothing is getting printed out at the moment.
Thanks for your patience in helping to resolve this! We'll get it sorted out quickly on way or another.
