Hello,

You have very old theme and plugins versions. You need to update first! It’s very important for the site to run ok and be secure.

To update theme, go to your Envato > Downloads and download theme again, lik eyou did the first time.
-Unzip the main file and extract theme folder.
-Upload it into your wp-content/themes folder. Rename the current theme folder in case you have made any changes to it.
-Go back to wordpress dashboard > Appearance > Themes. Activate the new copy.
Now you will be able to see a message in the dashboard requiring you to update included plugins. Follow the instructions and update every plugin.
