Without seeing the page you're debugging, I really don't know. Can you post or private message it to me? That error is when there are 2 extensions trying to add Open Graph tags, but I don't know what the other one is or how to fix it without seeing the page.

One thing you can try is moving our JFBCSystem plugin to the last (highest number) ordering position. With the v4.3 release, we've added some functionality to remove duplicate tags and only use ours, but it's possible it doesn't always work.

Let us know how that goes,
Alex

Hello Al, I tried to move the plug-in but nothing.

I send the data to enter the domain and see. Thank you.

Ligend,
Thanks for the credentials and letting us see what was going on. I think I see the issue and it's a complication of having both JFBConnect and JLinked installed. Could you try the following code change on your site, which should disable the extra set of Open Graph tags?

In the /plugins/system/jlinkedsystem.php file, around line 186, you'll see the following line:
$this->_replaceGraphTags();
Comment that out by putting two slashes // in front of it.

Hopefully, that will fix you right up, but if not, let us know!

Thanks,
Alex

Ligend,
Actually, we investigated further and found the actual cause. It's a pretty quick change to JFBConnect and will be something in our upcoming v4.3.1 release as well. Please edit the /plugins/system/jfbcsystem/jfbcsystem.php file. At line 487, you'll see:
$contents = $openGraphLibrary->removeOverlappingTags($contents);
$contents = str_replace($placeholder, $graphTags, $contents); 
JResponse::setBody($contents);
Update that to look like the following:
$contents = $openGraphLibrary->removeOverlappingTags($contents); 
$contents = preg_replace($placeholder, $graphTags, $contents, 1); 
$contents = str_replace($placeholder, '', $contents); //If JLinked attempts to insert, ignore 
JResponse::setBody($contents);
Let us know how that goes, and good luck!

Thanks,
Alex

Actually, replace the code with the following code. We found a mistake with the change above:
$contents = $openGraphLibrary->removeOverlappingTags($contents);
$search = '/' . preg_quote($placeholder, '/') . '/';
$contents = preg_replace($search, $graphTags, $contents, 1);
$contents = str_replace($placeholder, '', $contents); //If JLinked attempts to insert, ignore
JResponse::setBody($contents);
Sorry about that. We'll be testing more before the release of v4.3.1, but would love your feedback ahead of time as well!

Thanks,
Alex

Awesome! Thanks for the feedback to let us know it worked! That change will be in the next release of JFBConnect, so you won't have to worry about this issue going forward.

As for the og:image, there's a few ways that parameter can be set. If you're using the Open Graph plugins that are now a part of JFBConnect, they will try to automatically set the image if you're in a supported extension. In a Joomla article, for instance, the Open Graph plugin will automatically choose the first image in the article and set the og:image tag. The Open Graph plugins work for a variety of extensions.

Additionally, in an article or any other page, you can add the tag below which will set the specific image you want for that page. That's good in case the automatic image doesn't work, or you want more control of the selected image:
{SCOpenGraph image=http://site.com/link-to-image.jpg
Hope that explains, but if you have other questions, just let us know!

Thanks,
Alex

Good. But my problem are only on frontpage of my site.
In all componente, K2, Jomsocial Datso etcc... it's work fine, but when try to share my intro page ... www.21dieci.it ... i can not found any images.

I try to insert this string on my index.php?
Or set this on general features on JFBConnect?

Thanks

I wouldn't do it in your index.php file. I'd recommend going to the Open Graph -> Settings area of JFBConnect. In the "Defaults" box, add:
image=http://site.com/good-default-image.jpg
That image will then be used on all of your pages as a fallback if no other image is defined. That's great for a logo or other good 'generic' image to represent your site.

Beyond that, you can create a Custom HTML module and have it only display on your home page. Disable the title, and in the HTML area, just add the following text:
{SCOpenGraph image=http://site.com/good-image-for-home-page.jpg}

Hope that helps,
Alex
