yeah, it seems lastpass fills in the password and username in to the boxes successfully, but when you click on the log in button, that's when you see the error message saying "you could not log in due to temporary network problem"
but i figured how to make it work by doing following action.
1. when the boxes are automatically filled up, delete the last digit of your password and re type it manually and click the log in button. --> success.
2. when the boxes are automatically filled up, click on the laspass icon on your browser and click Autofill button (it is blue, arrow shaped button located at the bottom line) and have your id and password refilled in to the box. -->> success.
anyway i could not success by following any natural course of procedure.
do you have any solution other than these ad-hog measures aforementioned?
