1) My aMember installation (saliu.com/amember/) does not have .htpaccess. I wonder if it is the reason for this latest error 301(ERR_TOO_MANY_REDIRECTS) that popped up last Saturday, February 6, 2016… and continues as we speak… and I get angry emails from customers…. 2) I want to upgrade my aMember installation. How do I know that aMember 4 works with my site? I only have tester.php for version 3.2.3. PHP version: 5.3.29 (cgi-fcgi) MySQL version: 5.5.44 I also get a database upgrade error: Please upgrade your SQL database, upload latest file amember/amember.sql then run upgrade script Your database has version , your aMember requires [320 aMember Database Upgrade Current database version:  (may be different from aMember version number). Version of amember.sql file is .
