Images are NOT showing - Not able to login with FB credentials

Hi Alex,
so, with "Open Graph - Custom Object" and "Open Graph - Content" plugins Disabled.

In first of all I went in my plugin manager and re-ordered:
Content: "Content - JFBCContent" plugin as the last one, so sure *after* any Seblod plugins ("Content - SEBLOD" that have to be the first in the list for Seblod)
System: "System - JFBCSystem" plugin as the last one, so sure *after* any Seblod plugins

Now, I went to the Facebook Open Graph Debug Tool and entered my URL, clicked on "Debug" and then on "Scrape Again" and I have back 4 Warnings:
1 - Inferred Property = The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.
2 - Like Button Tag Missing = og:image is missing. The og:image meta tag is necessary for Facebook to render a News Feed story that generates a high click-through rate.
3 - Meta with name instead of property = The meta tag on the page was specified with name 'author', which matches a configured property of this object type. It will be ignored unless specified with the meta property attribute instead of the meta name attribute.
4 - Mismatch og:url and canonical url = og:url tag in the header is not the same URL as rel='canonical' link in the html.

So, I Enabled the "Open Graph - Content" plugin, went to the Facebook Open Graph Debug Tool (my URL was yet there), clicked on "Debug" and then on "Scrape Again" and, in first of all :cck: Intro + Full Content tags and Text are still there (nothing is changed), then, I have back 2 Warnings:
1 - Meta with name instead of property = The meta tag on the page was specified with name 'author', which matches a configured property of this object type. It will be ignored unless specified with the meta property attribute instead of the meta name attribute.
2 - Mismatch og:url and canonical url = og:url tag in the header is not the same URL as rel='canonical' link in the html.

Hooping on your help... thanks

Hi Alex,
No, I don't use any SEF component. Seblod have some internal SEF functions. So, I went in Seblod > Options > Site > SEF (Canonical URLs): and moved from Yes to No
I Enabled the "Open Graph - Content" plugin, went to the Facebook Open Graph Debug Tool (my URL was yet there), clicked on "Debug" and then on "Scrape Again" and:

1) Looking at our code, we ask Joomla for the content from an article ID. We're not parsing it out after it's been rendered on the page. That's important because, again, we don't know anything about Seblod, so our plugin doesn't have any idea that the ::cck:: tags shouldn't be there. I'm not sure how this worked on your site before. Are you sure it was working properly and, if so, what's changed since then? Nothing in JFBConnect has been changed regarding how we generate the tags from Joomla content.

Logically, all :cck: Intro + Full Content tags and Text are still there (nothing is changed). Is there a way to have it work properly ?
A - I noted also that you add all the intro and a piece of full content. Is there a way to choose if only with intro and / or full content ? ...the words quantity... etc. The most important would be at less to be able to set only "Intro".
B - Does it follow the joomla article permissions "Access" ? If is not set as "public" Arethe words showed anyway ?
C - We have the same ":cck: problem" with Content Filter plugin we are using...

We should, if the other extension is setting it properly, and use that as the og:url tag as well. Are you using any SEO extensions on your site? If not, that tag is probably being set by Seblod as well.

I have back only 1 Warnings:
1 - Meta with name instead of property = The meta tag on the page was specified with name 'author', which matches a configured property of this object type. It will be ignored unless specified with the meta property attribute instead of the meta name attribute. = still there, Is there a way to have it work properly ?
2 - Mismatch og:url and canonical url = og:url tag in the header is not the same URL as rel='canonical' link in the html. = seem to be solved (hooping can help you on your investigatings).

Many Thanks for support,
Emiliano
