I'd like to upgrade to Plesk 7.5.4; however, there are number of reports suggesting that the upgrade creates problems instead of address existing problems in earlier version. http://forum.sw-soft.com/showthread.php?threadid=26635 http://kb.swsoft.com/article_17_921_en.html q1. Can you safely upgrade to Plesk 7.5.4? q2. I seem to be having a problem with Tomcat. Does Plesk 7.5.4 solve existing Tomcat problem(s)?
