I am currently LOCKED OUT of my own website over this stupid plug in. My settings are set to 300 seconds as well, it has taken me 15 seconds to complete the log in information and math equation and the time expired error still pops up.
I am furious! So much so that filling out this math problem or this comment is pissing me off.
