Preview of a thread not showing on facebook

[ZUCCO]

When I post a link of a thread of my forum on facebook it showed a preview of the thread like the first paragraph of the thread itself but now it shows the meta description of my forum.

How to fix it? thanks

vb 4.2.2

Is this something that started happening after you installed the mods mentioned here, https://vborg.vbsupport.ru/showthread.php?t=308319

I think so, I tried removing the code but still

Have you tried with all mods disabled?

Same problem :(

Like you said it might be because I added those facebook comments lines but I removed those lines already and turn off all plugins but still. I know this because new threads show meta description but old threads created before I added facebook comments show the preview.

I cleared system cache and same.
