I'm pleased that you had no difficulty, me, still a problem.
I am using the Google Chrome Add-in for LastPass. When I click on that icon, it provides a drop down that I can expand to my entire LastPass vault. It looks like ImageA (attached). If I use that same icon, AND the site I wish to go to is at the bottom of the small window (not the vault full screen window), I get yet another window. From there I can Edit or Auto Fill.
If I click on Comedy Central edit, I get the image as in Comedy Central LP. Now that information is clearly shown to auto-fill.
When I go to the vault, click on the name Comedy Central, Last Pass will bring me to the site, but it will not Provide the information for log-in. It is not that it enters the information and Comedy Central rejects it, it does not enter anything. I did read the page that you sent me as a link, but that seems to refer to data that was entered and not accepted because it may have been out of date. I am also confused with your recommendation to delete the search and term fields. Where does the Search and Term fields appear? AS you can see from the attachments, I don't have and Search or Term fields, at least none that I use.
In your message to me you said "LastPass Icon -> Tools -> Save ALl Entered Data". Where can you see Tools? Where can you see Save All Entered Data? I have NEVER seen those options when trying to get things entered. Usually, I go to a site, enter my Username and Password and Last Pass asks if I want that information saved. That appears as a color bar just above the sites window. I say yes. I have problems after that. When I go to the site, and ask to change the password to a strong Last Pass password, is when the wheels fall off the Last Pass wagon.
If you will, please go into the posts, find the ones I have written, where no one has responded, and teach me what I am doing wrong. VERY disappointed with LastPass.
