The first strange thing to happen was after trying to install an addon by uploading the xml file (after uploading the folders and files as with any addon install process), I get errors saying no such files exist. I thought at first it was the addon but tried other addons to test a theory. The result was that all addons will not show to exist after I try to install them. Next, I'm trying to upgrade the forum to the latest version 1.5.8 and after uploading the download (chose the upgrade version), I go to the /install/ page and get the following: You are already running the current version (1.5.4). To do a fresh install, click here. (Rebuild Master button) I don't know what's going on here. Any ideas one what this could be caused from?
