Hello,
I just installed WHMCS 6.2 and I can't save the General Configuration area, I can see it.
I searched and couldn't find anything helpfull and changed php settings but without success.
I modified max_input_vars ( till 3000 ), suhosin ( even recompiled without suhosin ), max_post_size and I think there are more.
The error is "Connection reset".
Any suggestions?
