Attempted this evening to install elgg in http://terrywassall.org/elgg/. As you will see, there is no formatting and, although I am familiar with earlier versions up to 0.8, I cannot find how to find or change themes in the default installation. I assume it comes with at least 1 default theme. I understand themes are listed with plugins but there is nothing in the plugin list that sounds like a theme.
Up to this point installation went well. I downloaded and unzipped the files and used ftp to upload them into terrywassall.org/elgg/. I created a database and user as required. I created a data directory outside of the elgg root directory http://terrywassall.org/data/ and set the permissions asked for. Then I navigated to http://terrywassall.org/elgg/ and the install script ran as I had expected. I manually created the .htaccess and setting/engine.php files copying and pasting the text the installation script gave me. Then, on refreshing the browser to bring up the log in page I registered a user. According to the installation instructions the first user registered becomes the site admin. Having registered I logged in and enabled all the plugins that come with the install package. After spending an hour trying to work out if I could activate a theme and looking on the web for information I have given up for the evening. I’ll try again tomorrow and see if I can locate some help.
