I received the white screen on adding a range of ip to block. On deactivating plugins I discovered the problem was wp security. On removing the last range it worked well again.
Working ranges and ip’s
220.181.108.000 – 220.181.108.255,123.125.71.0 – 123.125.71.255, 180.76.5.0 – 180.76.5.255,46.118.152.23 , 91.200.13.0 – 91.200.13.255
Failure ranges and ip’s
220.181.108.000 – 220.181.108.255,123.125.71.0 – 123.125.71.255, 180.76.5.0 – 180.76.5.255,46.118.152.23 , 91.200.13.0 – 91.200.13.255, 120.40.149.000 – 120.40.149.255
Is there a limit to the number of ranges?
