Joomla Free extensions

Hi,

I share my blog on Twitter and LinkedIn with the free version of JO Social Share. It always worked fine, until the end of January, but all of a sudden the pictures and intro text are no longer shown if I share a blog on LinkedIn or paste a link on Google+ or other site. Links to images are broken. I'm not sure if it is Jo Social Share or something else. Has there been an update of JO Social Share? Is the problem solved when I update with the payed version?

1. You can see the broken links on my Google+ pages: plus.google.com/+MarcommattersNl/posts
Links I share from other sites are fine, but from my own site are broken (one I repaired by publishing the image on Google+)

2. You can try it by sharing one of my posts on LinkedIn: www.marcommatters.nl/index.php/blog

3. When I go to Extension manager, all images of the available plugins/modules are broken (see attached screenshot)

I cannot find the problem. My provider tells me it is a Joomla problem, not one they can solve.

My site: www.marcommatters.nl
I use:
Template based on Gantry
Gantry v 4.1.27
Joomla 3.3.6
PHP 5.4.33
Jo social share 3.1 (free version)

Hope you an help, because this is really a big problem, I need to share my content.
Kind regards,
Gerda

Hi Bach Pham,

Thanks for your response.

#3 I see the Joomla message now.

#1 #2: I now no the problem can be solved, very good!

But, I have no idea how to do this. I'm not a web designer.

And I never did this before. When I installed the JO Social Share everything worked fine and I did not need to edit the code. I publish a new blog every week. Is there not other solution? Just update the plugin? Or buy the basic version and update the free one?

I only need to share and let visitors share my blog and articles on LinkedIn, Twitter, Facebook e.d.

Looking forward to your respons
