[Plugin: LinkedIn SC] Information profile not displayed

hi! I’m trying to use linkedin-sc
I installed the plugin following the instructions provided on the site and I activated it.
After this I created a new page and I pasted the following code in the guide (html mode).

[linkedinsc profile="guillaumev" lang="en"]
<h2 style="text-align: center;">[linkedinsc_status]</h2>

<h3>Experiences</h3>
[linkedinsc_exp]
<div style="float: left; width: 150px;">[linkedinsc_exp_start] - [linkedinsc_exp_end]</div>
<div style="margin-left: 150px;">
<b>[linkedinsc_exp_title]</b>, <a href="[linkedinsc_org_link]">[linkedinsc_org_name]</a>
<em>[linkedinsc_org_sector]</em>
[linkedinsc_exp_description]
</div>
[/linkedinsc_exp]
<h3>Education</h3>
[linkedinsc_edu]
<div style="float: left; width: 150px;">[linkedinsc_edu_start] - [linkedinsc_edu_end]</div>
<div style="margin-left: 150px;">
<b>[linkedinsc_edu_title]</b>
<em>[linkedinsc_edu_degree] in [linkedinsc_edu_major]</em>
[linkedinsc_edu_notes]
</div>
[/linkedinsc_edu]
<h3>Computer skills and languages</h3>
<div style="margin-left: 150px;">
[linkedinsc_skills]
</div>
<h3>Personal interests</h3>
<div style="margin-left: 150px;">
[linkedinsc_interests]
</div>
[/linkedinsc]

When I go to see the page from the front end, I read only the following words:

Experiences
Education
Computer skills and languages
Personal interests

No additional information

I tried to change linkedin address but nothing changes.
What can I do?
