Thank you,
please remove that code and try with this one instead:
.et_pb_text > :last-child {padding-bottom: 15px;!important}
If that does not work, I will need to take a look into your WordPress Dashboard. Please download and install our "Elegant Themes Support Plugin". This will allow me to access your site securely.
Once you have the plugin installed and activated go to Tools > Elegant Themes Support Account > Click on "Generate New Token”. This will generate a token which you can copy and send it to me:
Elegant Themes Support Plugin URL:

Thank you for your cooperation.
