We have found that you are using a critical outdated theme and Visual Composer versions.

Since you cannot use the auto-update feature, in order to update Visual Composer plugin you will need to:

1) Access `Dashboard -> Plugins` and deactivate/remove Visual Composer plugin;

2) Go to `Dashboard -> {theme_name}` and click on `check for updates` button then follow the `Updates` page: https://drive.google.com/a/teslathemes.com/file/d/0B-OaWUxuHvUOWElYbW9WOEZJYlU/view?usp=drivesdk

3) Once there, please choose to update the {theme_name} theme;

4) After the update, you should get a Dashboard notification about `the required plugins installation` Please install and update Visual Composer using the installer wizard;
