gallery2 képfeltöltés probléma

szecso képe

Sziasztok.
A szerverre felmásoltam képket és azt szeretném betenni galériába. (gallery2)
Mi lehet a gond? mit kéne tennem hogy menjen?
Előre is köszönöm a segítséget.

De ezt írja ki:
An error has occurred while interacting with the platform.

The exact nature of the platform error is unknown. A common cause are insufficient file system permissions. This can happen if you or your webhost changed something in the file system, e.g. by restoring data from a backup.
