Hi,

I just changed few settings in my Hikashop config (can't tell which one for sure, cart flow, some currency info, shop info...) and I got this error:

now each time I'm trying to visit Configuration I'm receiving above error. Already tried to install Hikashop over the existing (using Extension Manager), but still error occurs. I removed Hikashop and istalled it again, now it works, but why did this happen?

Hi,

Hard to say. It could be anything as this is a generic MySQL query to load a category.
The 'Array' indicates that something relative to categories was wrong but can't say more. It could be almost anything.

hi
I also have a problem comparing . When I want to compare the two products, I'll go through this error.

Hello,

You should enable the Joomla debug mode to get the "call stack" and provide us precise indicate of there there issue is.
Please understand that there is thousand of queries within HikaShop (about 1600 just for the core) so we need to have more details to investigate properly.
