check ./logs/errors ... most likely it is a php memory limit or a post size restiction issue.
thanks for the quick reply, it does seem to be the case. how awkwardly it only happens to compressed files like ZIP and RAR's.
below is the output in the log, btw how do we increase the allowed memory to be used for Roundcube? i have 1g physical memory on the server.
