Hi there,

I am sorry for the delay of this reply. Kindly please find my response to your inquiries below:

1- If I try to preview the post ("Preview Post" button menu), I get the attached ErrorOnPreviewPost.PNG.

->After a while troubleshoot, I've inspected that the System - JFBCSystem Plugin is the caused of the error. I've temporarily disable the System - JFBCSystem Plugin and the blog post preview is working fine now. Please give it a look

2- If I add the existing tag "Grand Rendez-Vous" and then hit the "Save For Later" button then I get the attached ErrorOnSaveForLater.PNG. This seem to happen for this tag only.

->I've tried this in your site and locally, it seems there is a bug where when there is a 'dash' '-' exist in a tag the error will appear. This issue has been logged in our issue tracker and our developers will take an action on this.

Thanks for understanding

Thank you

Regarding issue 1-, it seems to be there is a conflict between EB and JFBConnect, but this does not tell me on which side the problem is Could you investigate just a bit more?

Hi there,

It is the Open Graph - EasyBlog plugin by JFBconnect did not get the category Id.

Oh OK, this is JFBConnect doing this wrong SQL query.

There are several issues on blog post preview in frontend, in particular when JFBConnect and sh404SEF are used. I will investigate this a bit more and come back to you with a list

OK, I created some topics for the other issues I found.

Regarding the issue with JFBConnect, this is because JFBConnect is expecting to find the id of the blog post in the preview URL, whereas preview page URL looks like:
index.php?option=com_easyblog&Itemid=781&lang=fr&layout=preview&uid=113.253&view=entry

This id is then used to find what is the category of the post (and maybe some other post information) to build Open Graph tags.

What would be your advice to SourceCoast (which develops JFBConnect)?

Hi Altitudes,

I am really sorry for the delay of this reply.

I have applied some suggestion fix inside /plugins/opengraph/easyblog/easyblog.php under method @findObjectType so that the plugins can get a proper blog id and use it to load the blog post. Please have a look.

Thank you

I have given all the information to SourceCoast, here:
