[Plugin: Local Market Explorer] Installation Generated 175 Unexpected Characters…

I deactivated and deleted the plugin, then re-installed it and received the following WP error: “The plugin generated 175 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.”

I do not see any adverse effects when using the plugin.
