Before anything else, please check this with no 3rd party items activated, and also ensure you are using the latest release of the software

It sounds like PHPRedis may be returning an unexpected value on your server (this value should always be an array, whether it's empty or not).

We'll make some minor robustness changes in a future release to handle this situation though.

Edit: A workaround in the meantime would be to disable the 'Use Redis to reduce MySQL overhead' setting in your data storage configuration

Thanks a lot, it's ok now.
