[Q] Not enough space on device topic

Hi, I haven't been able to download or update my apps from Google Play Store for quite some time now, due to the following error: 'Not enough space on device'. I do have enough space on both internal memory as on the SD card.
I'm the (proud) owner of a Xiaomi Redrice (model HM1W)
Android version 4.2.2 HM2013023
MIUI version MIUI-JHBCNAH4.0

I don't know what other information you guys might need.

I really hope you guys can help!
