Method 1: Installation with ftp access
You can connect JivoChat to your site through its source files, using an ftp-client.
Navigate to: Main Folder/Themes/Your site template/footer.tpl
Open the footer.tpl file and paste the JivoChat code before the </body> tag.
Make sure to save the settings, and you’re done!
The JivoChat code is available in the JivoChat admin panel, in the Installation section: Sites -> Settings -> Installation.
You can also reach the JivoChat code through this direct link: https://admin.jivosite.com/widgets/installcode/
*Note: If you have some trouble after installation, try installing the JivoChat code in the header.tpl file as well, before the </head> tag, and save the settings.
Method 2: Installation using the Contentbox Module
Before you begin, you need to download the module from http://contentbox.org
Then, go into your PrestaShop admin panel and navigate to the Modules section.
Modules -> Add a new module.
Choose the downloaded ContentBox file and click Upload this module.
Find the uploaded ContentBox module in your list of modules, and click Install.
Next, open the ContentBox module settings.
Click HTML -> Edit HTML source as pictured below, and then paste the JivoChat code into the field.
Make sure to save the settings by clicking «Update (Save)», and you’re done!
