Opencart header editing does not work in the live website

Question

I install opencart locally and edit the header. Changes are shown but the same file I put in the C panel just header changes are not working. Other all pages show the modified work except the header. Even I delete the header file but the default opencart was also shown. From where default header comes? In the admin, these errors are shown PHP Warning:

unlink(/home/zeromyvb/smartview_storage/cache/cache.stock_status.1.1638804472): No such file or directory in /home/zeromyvb/smartview.com.bd/system/library/cache/file.php on line 17

Answer 1

Examine permissions and the path to the DIR_STORAGE directory within the config.php and admin/config.php files and replace the relative path with an absolute path for DIR_STORAGE.

Answer 2

before > check DIR_STORAGE & DIR_SYSTEM in config.php

1- remove all cache files from > root/system/cache/*

2- remove all modification files and folder from > root/system/modification/*

3- run refresh modification link in admin section

4- check folders permission > logs + cache + modification

Answer 3

In OpenCart Admin go to extensions/modifications and press the refresh button a few times.

On slower servers you might have to wait a minute.
