Problem with ini_set

[hcmls.net]

My host disable ini_set, so I must disable ini_set in file vb/vb.php because if not, forum cannot run. But, when I dis it, I cannot post thread too long; when I post a thread too long, it's empty. I'm very furious that. Can I fix it?

P/S: I cannot change hosting. Thank a lot.

How is it empty? Screenshots of you posting a long post, then after submitting its empty.
