Hi Micheal,

I believe this error just explained to you someone trying to access one of the blog entry page, but this user doesn't have permission to access this post, so Easyblog throw 400 error on the site.

Based on what this error message, it seems like something related with the EasyBlog - Auto Article plugin.
Can you try create a new this post from Easyblog and see if you still getting this error from your email?

Before you create a new post from your site, you can temporary disable your Facebook autopost feature from your site backend > Easyblog > autopost > Facebook .

I disabled "Auto Posting" to Facebook and I did NOT get any emails with PHP errors.

Hey Michael,

Currently you are the one who create new article post from Easyblog right?

If yes, perhaps you can enable back those autopost setting then try publish a new blog post next time, and see whether still getting those email notification regarding these error?

But you have to monitor it like when you publish a new blog post, do not edit the existing post first, and see whether later have receive an email notification regarding this or not.

If don't have, then have to try edit the existing blog post and update it, see whether later have receive an email notification regarding this or not.

Keep us update regarding this.
