I'm really new here but not new at all in this business: I know there are only two rules:
1) if you don't earn, we don't earn
2) if we don't play, you don't earn
I'd like to vote +1 this comment but there is no voting/like system on bitcointalk

Have patience until mellowads fixes their stuff.
Mellow ads are amateurs ; lots of errors and complaints scatterred on internet since Cretaceous

P.S. - lottery tickets worked for me for some hours, two days ago, since then only blank php page
I haven't tried lottery lately but if the blank pages issues are resolved, tomos would most probably recommend you to hit F5 or clear cookies (note : clearing cookies might ask you to relog on websites)
Yeah, you got it, I don't earn, you don't earn, you don't play, I don't earn, but.
With 1 BTC worth of ads I can push this site on top of google search term I need it to rank for, so, it's a sword with 2 edges.
I just need to let the site sit and flow on its own, so I can see short term results from ad companies, in order I can increase/decrease rewards and make sure this site will run forever.
Spock says that this is perfect logical

just don't keep reducing rewards so the website won't enter in "survival mode"
