trouble with Suhosin?

I’ve read the numerous posts about how we might solve the problem with using large tables and the Suhosin php extension, but so far haven’t found a solution. We have an table with 23 columns and 393 rows (so about 9000 cells) and the rows will increase with time. I’ve asked our webhost to increase the suhosin.request.max_array_index_length and suhosin.post.max_array_index_length settings from 64 to 300 and 400 but it hasn’t worked – big tables cannot be edited and saved.

Our php info is at whichetf.co.uk/test.php
Might anyone be able to shed some light on our problem? Which other settings need to be changed? (As our webhost refuses to disable the Suhosin plugin altogether)
