edit.php file do no show all my post and pages

Hi,

I can’t see my posts and pages in the admin panel.
I see the posts are in the database but I can’t see them in the admin panel.

It shows the total number like this, but no post is listed below:
All (310) | Published (305) | Drafts (5)

The theme is showing the posts and pages correctly, but I can`t edit them in the admin panel since they are missing.

I’ve tried the following to resolve the issue:

– I repaired the database in phpMyAdmin
– Re-installed WordPress twice
– Deacivated pluguins
– Change the theme to prove that is not bad code

And nothing changes. Please help me, I’m running out of ideas.
I′ve read some posts about it in this forum but I haven’t seen any with a solution.

Thanks
