We manage to resolve the issue. The cache module (cache.so) was not updated. In this case you can download Openlitespeed and configure it in different directory. After that just copy the cache.so (from lsws/modules).
Hello again,
Can you check if the command setting is correct - check if there is file $SERVER_ROOT/fcgi-bin/lsphp-5.6.33. In most cases this will be only $SERVER_ROOT/fcgi-bin/lsphp
