I downloaded PHP and have the zip folder on my desktop. Go to install new plug-in, upload the zip folder, click install, and I get: Unpacking the package. Installing the plugin. Destination folder already exists. /home/content/22/5228622/html/wp-content/plugins/phpBB3/ Plugin Install Failed. Anyone know what's going on here? I tried deleting and redownloading all the PHP files and I still get the same result.
