Hi,
we still have the same bug in version 1.5.3
A lot of people in der DE-Community have the same bug. So will our backup not work, because we are not able to extract zip-file from the backup.
Please have a look at it. Zip is in php avaible, but it will not work. So we think it is better to disable all Zip-Functions in OpenGoo.
Sorry but this is a very strong bug in OpenGoo.
