There was an error uploading this file to the server.
Maximum PHP file upload size is too small: This is set in php.ini in both upload_max_filesize and post_max_size settings of your PHP settings (located in php.ini and/or .htaccess file).
Unable to find install package
Have reset both max upload and max size settings to 20M with no success.
Be careful about buying an extension you cannot install.
Got the installation to work after unzipping the membership file then installing from the tmp folder. Directions were not clear in that two files needed to be unziped before the installation was complete.
