How to change header of opencart site?

Question

CMS

I know where to find the header.tpl file, but after editing the site, there are no changes. How to solve this problem?

Answer 1

The problem was solved by updating the modifications in the admin panel. Thanks to all

Answer 2

Clear cache.
If vqmod is installed, clear the vqmod /vqcache/ folder!
If just opencart then the system / cache / folder (leave only index.html)

Answer 3

Here, apparently, the template that used the modifiers, you need to update the modifier cache.
