Thank you for trying this new plugin.
The plugin shows very clearly that this is a beta, there will be the occasional issue.
What do you mean when you say it requests php version 5.3?
There is an "exit" in php to stop the plugin being used any further, however it should only happen when looking at the plugin pages. Clicking back in your browser and going to another WordPress admin page should work fine. However I will look at that again, probably remove the "exit()" and just display a message.
I'm not sure what you mean about the hosting, could you make it clear what your doing please. I can't see how the plugin can send you to another page, after it shutting your WordPress blog down. It would need your blog to be running to perform such actions.
Also the hosting could be our hosting service.
There is a lot more to come for this plugin, any time you spend trying the next version is appreciated.
Thank you for your feedback, your probably the first on this forum to give any.
