Missing compacted block file. Weird case

[scashcoin]

I am trying to make the web wallet work on time but without success, everything is fine and the web wallet works but does not synchronize the blocks, this error appears.

command:
http://domain.com/blockchain.php?gen=1

error:
scanning 0 to 50
int(0) scanning 50 to 100
string(40) "Missing compacted block file. Weird case"

I have already tested several code sources such as qwertycoin, parsicoin, masari and karbowanec but all of these errors occur.

any idea what this might be?

thanks.
