Hi, There could be some javascript error on the ExtensionManager.
It would help if you would right click and select "Inspect Element", select the tab "Console" from the frame that appears below and reload the page. If you get some (red) errors in the "Console" tab while retrying your operation, paste them here to give us an idea about what is going on wrong on the Extension Manager side. Regarding the extensions you are trying to install/uninstall, there is a chance that the operations were successful, only that the javascript error prevented you from getting the right feedback in the Extension Manager UI. Try to clear your browser`s cache or, as a last solution, maybe restart your XWiki instance. These are really not issues of the extensions, but they look like some issues of the Extension Manager UI. Hope this helps, Eduard On Thu, Feb 11, 2016 at 4:15 PM, Sonic <timurale...@gmail.com> wrote: > 1. > I have tried to install Syntax Highlighting Application(3.3 version) after > I > deleted the one(3.1 version). > Extension manager just started showing this icon: > <http://xwiki.475771.n2.nabble.com/file/n7597917/2.jpg> > The install log was empty.
