If it were the big orings that you can see then the bottom cap of the tank itself would be messy.
First clean the top part of the Provari real good with quips and some alcohol. Take the tank by itself and holding it upside down so there is no juice covering the wick holes blow the excess liquid out into a paper towel. Take the paper towel then and make sure the connector on the carto is completely clean and juice free. I would then find something to set the tank upright over a paper towel for a little while to see if anything is leaking out. If nothing is leaking then you may have just had a flooded carto. If there is juice leaking out then the inside bottom oring probably needs to be replaced.
If the carto continues to flood then one of the inside orings is not sealing completely or your carto is too old and needs to be replaced.
All this is assuming you're using something like a DCT. Hope that helps.
