I have pmwiki flawlessy running on php4 since years. Now my (shared) hosting is switching to php5. As far as I read here http://www.pmwiki.org/wiki/PmWiki/PmWikiFeatures there should no problem at all. Just I'm scared by that green notice telling about the MMCache. I'll enquiry the hosting about it, but what if it is not disabled? Thank you Luigi
