home_default image size won't change

[horuss]

I'm trying to change the size of the product images on my home page.  So I went to image settings and changed from default 250x250 to 600x600. I regenerated thumbnails. Images stayed the same 250x250 although in home_default image settings is new value 600x600. Im using classic theme and prestashop version 1.7.6.8. 

Any help will be much appreciated

Maybe the image size is limited by the template grid?

maybe. if so, do you know how to change it?

Please make some more effort. When Joseantgv says this the suggestion is clear that you should do your homework and look at your website. It might contain something like "<img width=250px".

btw: did you clear your cache?

mate I would love to do my homework but have no idea where or how to change the template grid. I searched on forum how to change the image size on tpl file but couldnt get any answers. When I change size of other image type like large_ default, it works ok. When I increase or decrease the size of home_default it does nothing. So probably I have to change the size in .tpl file but is it supposed to be product.tpl or shall I change it somewhere else? cheers
