XF 1.5 Forums disappeared after restore

[Miacommunity]

I had to back up a database but for some reason the many sections of the forum I created have disappeared both from the forum and from the admincp, although they are present in phpmyadmin.
Why all this? How can I fix it?
Thanks in advance.

How did you backup the database?

 

[Miacommunity]

with a backup.php that made the backup of all tables, then i restored with a restore.php, via browser.

Does the data exist in both xf_node and xf_forum?

 

[Miacommunity]

in xf_node there are just three forum, but in xf_forum there are all forums that i created.
But i launched a global backup, table by table.

Sounds like your backup script didn't actually back everything up then, do you have another backup that you can get the xf_node data from?

I don't know what backup.php is, but I suspect that is the issue. In order to properly backup a MySQL database you must use mysqldump.

Simply i think i must reinstall. Poor me.
Thank you for the support and apologize for disturb.
