[xwiki-users] How to completely remove XWiki Enterprise

Hi users, Yesterday I was testing my java component and after I have deleted some pages from my wiki (I am running XWiki Enterprise 7.3) I started to get some errors and malfunctioning such as: I don't see anymore any pages under the "Deleted pages" index and when I try to delete some nested pages the wiki is telling me that the deletion would affect several childern even if those children are not diplayed anywhere. If I agree I got errors becase "I don't have the permission to delete them" even if I am logged as administrator. When I see that I am not even able to call the methods from my java component through the script service,( those method are in charge of creating new pages as well XClasses and XObjects) I have decided to unistall XWiki Enterprise and re-install it. Unfortunately I see that I have the same errors. Moreover after I have started the XWiki, before I click on the "XWiki Home" icon on my desktop, I have noticed in the terminal the following warnings: *[main] WARN ltInstalledExtensionRepository - Invalid extension [org.xwiki.platform:xwiki-platform-wiki-ui-common-7.3] on namespace [wiki:WIKINAME] (InvalidExtensionException: No compatible extension is installed for dependency [org.xwiki.platform:xwiki-platform-wiki-ui-common-7.3]* And I get this warning for each wiki that I have created BEFORE I UNISTALLED IT. After I try to call my methods (that should creates wiki pages Xclasses and Xobjects) it start working until I get a bunch of Exceptions and some ERROR 3002 and some ERROR 2002. The strange thing is that a couple of days ago it worked fine. So finally my question is how can I COMPLETELY delete everything that is related to XWiki Enterprise in my computer and then perform a clean XWiki Enterprise installation? I hope to get a quick answer because this is my master thesis project and I only need to perform some final testing as I am graduating in 40 days. Please help me in find a solution Giordano.
