Please Help

Hi I'm at my wits end with a 'L' shaped pan connector, I recently replaced the leaking pan connector only to find the replacement also started leaking, I checked the connnections but the leak has persisted. I since purchased another brand of the connector believing this to be the problem. It is not, no matter how much jigging or moving I do I still have a slow drip after flush.
Please help!

Is the leak coming from the connection to the pan, or the connection to the soil pipe?
Whats the soil pipe made from - salt glaze or plastic?
A pic could help here - maybe the labyrinth seal on the connector is being displaced, or maybe the connection diameters aren't correct.
