CM11 XperiaV whatsapp and others can not save files

Hi !

I installed CM11 on my XperiaV and all the apps like Whatsapp or FB messanger can not save pictures or files.
Read a lot of the threads regarding this problem but could not fix it.
The folder /data/data/com.whatsapp is there, but I think all the apps want to access sdcard0 for that???
But that is in read only filesystem mounted.
mount shows that:
/dev/block/vold/179:33 /mnt/media_rw/sdcard1 vfat rw,dirsync,nosuid,nodev,noexec
,relatime,uid=1023,gid=1023,fmask=0007,dmask=0007, allow_utime=0020,codepage=cp43
7,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
/dev/fuse /storage/sdcard1 fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1
023,default_permissions,allow_other 0 0
/dev/block/vold/179:15 /mnt/media_rw/sdcard0 ext4 rw,dirsync,context=u:object_r:
sdcard_external:s0,nosuid,nodev,noexec,noatime,dat a=ordered 0 0
/dev/block/vold/179:15 /mnt/secure/asec ext4 rw,dirsync,context=u:object_r:sdcar
d_external:s0,nosuid,nodev,noexec,noatime,data=ord ered 0 0
/dev/fuse /storage/sdcard0 fuse rw,nosuid,nodev,relatime,user_id=2800,group_id=2
800,default_permissions,allow_other 0 0

So the external card is FAT and the internal is ext4 over fuse...
Cyanogenmod 11 (11-20141112-SNAPSHOT-M12-tsubasa)

Any help would be awesome because that is really a bad thing those apps can not save anything!
