Nefunkcni stranky

Dobry den,
me stranky zloservis.wz.cz prestali v podstate fungovat...
hlasi to tuto chybu:

"
Warning: Unknown(): write failed: No space left on device (28) in Unknown on line 0

Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0
"

nastava to po pri prihlaseni uzivatele z me db asi pri registraci sessiony. Kontroloval jsem velikost db v mysql (2.1MB) a strankovy prostor je skoro nevyuzity...
