[Solved] No thumbnail and no image descrption issue

I have check the attachments i uploaded here and they have their name and a number all of them but on my site 12 attachments have no names or numbers and when i want to insert them into post i not know what photo name it have or extension it is missing see my first post.

I see names and IDs on screenshot. In any case if you don't have them it meant the real file name doesn't exist or the permission of this file is not readable. wpForo doesn't affect any file and you should search this issue out-side of this addon. If file is damaged, deleted or permission is set to low wpForo Advanced Attachment addon can't read and get all necessary data, it only shows the thumbnail located in /thumbnails/ subfolder of main attachment older.

What have wpDiscuz with this?
I have look the files are in the same folder even thumbnails are available but they are non usable when i want to insert in post because of missing number and names, the permissions are same for all files in my admin folder.
Also i observed if i edit those photos from server they move up see screenshot with missing and available names/id's of attachments.

Sorry I mean wpForo. As far as I mentioned in my last post something is wrong with these files. Addon works with the same functions for all files. I'm sorry but I have no other idea for your question. You should check files permission and header information. Maybe they are protected by authors or so...

Also make sure the _wpforo_atatchments table is not damaged or deleted in Wordpress database.
