Hi, Some time ago (few years, really) I working with Uniserver 3.2 (Apache 2.0.54, PHP 5.0.4, MySQL 4.1.12a, phpMyAdmin-2.6.3-rc1) and so far not had problems with compatibility. But now I need to work with php 5.2 and want to update all Uniserver. How to do this step by step?. What version from uniserver is the best for me? thanks
