As I mentioned somewhere, I reinstalled Zencart and was able to access the admin and other functions. I then installed Easy Populate 4. It appears as expected under Tools but when I click on it I get a "Secure Connection Failed" message in Firefox. Tried Chrome with a similar result. It is odd because php and the ssl certificate is working elsewhere on the server. Perhaps there is a directory that is configured with the wrong permission - but I would expect Easy Populate to say so. Very frustrated with this. Would appreciate advice.
