Hello,
I can't get more traffic per day!!! I'm can spend just $50 per day on traffic.
Why that?
You need to hit the $50 limit for a consecutive 3-5 days and they will increase the limit to $250 for you.
Add a cell number to your account and you get bumped to $250 right at the start.
today was my account bumped to $250 
If I spend $250 consecutive 3-5 days, they will bumped to $1000 a day?
Normally its $250 - $350 - $500 - $750 - $1000
But sometimes you get bumped to $2k after $500 or something. I've mailed them a couple of times asking for a bump, and I got bumped to $2k once and $5k the next time 
thanks for the info lifetweak

Please try resending your request.
This is probably not a bug in proxygen. Based on experience, either intern or latest is temporarily down due to a SEV or push.
Please check in e FYI or #e first.
If the error persists through retries, or if you have good reason to
suspect this is a bug in proxygen, please report the issue

Are you using a proxy to create the ads? I've also had trouble submitting ads while in "private browsing mode" in the browsers, not sure if you're using that as well.

It was like that this morning for a few people. Here's a thread about it.
