I have tried to build a free web, that use wp cms and hosted it on freeweb7.com, but just have a trouble in attaching the plugins, I was upload some plugins on the host directory, but I still couldn't see it, when I check it out on my web to activate, is there solutions?
Well I never used freeweb7.com or any other free host to install wordpress, and I don't know if you can able to access your space through ftp or other means. If you can, did you upload the plugin files to plugins directory inside wp-content directory which situated at the root. If yes, then you can activate the plugin from your wp dashboard and plugin settings.
