Prestashop 1.4.1 and FPM (fastcgi) - BACK OFFICE caching?

[rcking]

Have problem which I can't find solution. After upgrade server to FPM I am dealing with very strange behive of BO. When I do any change sometime is visible immediatelly (like before) but very often there is no visual change.

 

Examples

1. Change status order, page reload, but old status still there. Later (sometime 1 min, sometime half an hour) new status visible

2. Add new products to order, or delete some, or cancel items, loyalty vouchers / doesn't matter, still the same story, it looks like nothing happen

 

BUT when I look immeditally to db everything is wroten there very well. So it seems that BO use some cached results from SQL. But I always think, that there is no cache for BO, was I wrong? Or it some cache on FPM? My hosting provider told me it's application problem, not server setting. (we have own server).

 

Any idea?

 

Thanks.
