Immediately after logging in to LinkMachine, when I click on any link, I am logged out, and asked to log in again. Why?

One possible cause for this is that LinkMachine does not have permission to update its data files, so it cannot record the fact that you've already logged in. Make sure that write permissions are turned on for all files ending in ".dat" in your site's "linkmachine" directory.

LinkMachine uses browser cookies to keep track of whether you are logged in. First, make sure your web browser's cookie support is enabled. Next, make sure that your own computer's system clock is correct - especially the month and year. Finally, it's very rare but sometimes the system clock on the site's web server may be incorrect, your web host's tech support would be able to check that.

If none of these solve the problem, try using a different browser to access LinkMachine (for example use Internet Explorer rather than FireFox, or vice-verse) or try using a different computer.
