The plugin is installed the usual way: just extract the plugin ZIP file to wp-content/plugins. After activation, you will see a new sub-menu in WP-Admin menu.
WP-Filebase Pro requires you to enter your license key before you can use it. Click on the new WP-Filebase menu to activate your key. After activation the plugin is ready to use.
Goto WP-Filebase -> Settings. In the Common tab you can adjust the Upload Path. Make sure this folder is writable for the webserver, otherwise you won’t be able to upload files and WP-Filebase cannot create thumbnails. On Linux servers you can execute the CHMOD command via FTP:
CHMOD 777 wp-content/uploads/filebase
To use the search feature and category linking, it is necessary to set a File Browser Post or Page (see FileBrowser): Create an empty Post or Page with a title like “Downloads”, then go to WP-Filebase -> Settings, click on the tab “File Browser” and select the created Post/Page. The File Browser will appear on the selected Page where users can browse through categories. This page is also displayed in search results if there are matching files.
