Nemo, no change after I disabled the instant search. Moreover, that it's showing even when I'm not searching for something. You can let me know your IP if you want to take a look yourself.
Pascal, I've PM-ed you.
I just want to say that before I tried another E-commerce software (Magento) and back then my website crashed, couldn't index more products because of the limit of php memory of my domain. I am really afraid that this is happening again, however it may not. Let me know if you think of something.
Thanks
