Test with a wide selection of community plugins At the "Install plugin" admin page, when attempting to install a plugin ZIP package (downloaded from the Plugins directory or from the Github): Test that there is no need to explicitly select the plugin type in advance. If the plugin declares $plugin->component in its version.php, it is used implicitly. Only when there is no such declaration available, the admin is asked to select the plugin type at the next screen. If the admin is selecting the plugin type manually, and the target directory is not writeable, the warning appears. There is now a new "reload" link that let's you repeat the check. Make sure it works for you. The acknowledgement has been moved to the next validation screen. There is no need to check a box now. The warning should be just displayed.
