Apologies about the Inconveniences caused, however, we currently do not provide support for outdated versions of Canvas! And the Version you are using is more than 5 years old: http://docs.semicolonweb.com/docs/changelog/version-1-3-1/ and the Codes have extensively changed!
Currently we only provide support for Canvas Versions later than v5.x. Additionally, the issues on your Website are related to Customizations which is out of scope of Support included: https://themeforest.net/page/item_support_policy . While we would have loved to fix your issue, providing support for very outdated versions of Canvas is not possible as this would require us to go through the Older Codebases and then provide fixes accordingly. So, we would highly recommend you to Update your Website to the Latest Versions, keeping in mind the Security and Performance at play.
Thanks for Understanding.
