@melliflousvoice This is how it works:
Let’s say the 30 days without warning was reset today (which means you received a warning from Fiverr today), you will ONLY be eligible for a level up on the 15th of February 2019. You will, unfortunately, not be eligible for a level up on the 15th of January because 15th of January still falls within the 30 day penalty period. I hope you understand.
You also need to understand that you don’t get an automatic level upgrade as soon as you meet all the requirements for the next level. You have to wait until the next 15th of a month for the upgrade as Fiverr only reviews sellers’ accounts (to see if they’re eligible for a level up) once every month (on the 14th or 15th of every month). You also need to keep maintaining ALL THE REQUIREMENTS UNTIL the next 15th for you to successfully level up your account.
If you are unsure of why you received a warning (provided it is not a mistake on Fiverr’s end), I would suggest that you carefully go through Fiverr’s ToS and Policies. There’s nothing more dangerous than not knowing why you received a warning from Fiverr as that would open up the chances for you to unknowingly violate the ToS yet again!
I hope it is not too complicated for you to understand.
