Publish in front : problem with Preview button

There is no preview button in that screenshot and what is in the screenshot is not JFBConnect. Are you sure you've included a screenshot related to our products JFBConnect or SCLogin?

SocialDebug.com is actually one of our webpages, which shows how the page should render in the social networks. You enter your URL at the top of the page.

The social toolbar that has that Preview button can be disabled in the JFBConnect backend > Configuration > General area. By default, this is only shown to administrators that are logged in on the front-end, but you can disable it.

With the message : There was an error processing this URL: in a small font at the bottom of the window.

It looks like socialdebug is having an issue processing websites. We'll investigate it and get it fixed. Sorry for the trouble.

I don't see, i think that it's rather on parameters on ACL configuration : "Post on Social Network " rule, no ?
For SU you cannot disable a rule, but this is not the problem.

The setting in the Configuration area that you're looking for is "Enable Social Toolbar". That will disable the entire social toolbar and will hide it for super users and all other usergroups.

The "Post on Social Network" setting will also hide the entire toolbar, but lets you select which groups can see it (except super users always see it).

And isn't it possible to made a override of the template of this box (in this case just for chose to not display this preview button) and to translate all the button's messages?

We don't currently have a way to override each button. However, you can simply delete the thought what you can do is simply delete (or rename to anything else) the following file and the Preview button will no longer display:
/components/com_jfbconnect/libraries/toolbar/button/preview.php

I hope that helps,
