This is probably because Debug settings are switched to on in the extension parameters. Please open the LoginSecure Framework plugin into your Joomla! Administrator area > Extensions > Plugins.
- Search for "LoginSecure Framework" and open the plugin.
- Then in the tab "Settings" you will find debug options under "Framework Settings"
- Switch both the debug and debug mobile detect options to off.
- Now reload the pages that showed all those messages. They should be gone now.
- If not, then please create a ticket.
