WordPress bundles a version of jQuery. You will inevitably encounter problems if your Theme (or a Plugin) enqueues a separate version of jQuery - whether by enqueueing that separate jQuery version along side the WordPress-bundled version, or else by deregistering the core-bundled version, and enqueueing a custom version.
Don't register a custom version of jQuery via your Theme or any Plugins. If you need to use jQuery, just use the core-bundled version, via:

You're getting a JS error when trying to load the ticker in the single page:
Cannot call method 'totemticker' of null.
It might be conflict with another plugin, or the totemticket script is not set to load in single pages.
Can you add parts of the header.php code? and perhaps the single.php code?
