So, in order to insert a variety of scripts (google analytics, online consultant, counters, etc.), you must have the script or code itself.
After you receive it, you go through "Info pages / Pages / Blocks" and click "Update" next to the value "Scripts".
Before we open the window for editing, it needs to click "Source".
In the new window that opens, we insert the script itself (code).
If there is already an old Jivosite code in this window, you should delete it and insert a new code.
In order to save everything, click "OK".
