While playing around with OpenCart we were trying to create new OpenCart 3.0 theme and for that we copy the default theme and named as webocreation and was doing following setting but got an error.

Warning: You do not have permission to modify the default store theme!

So make following changes to solve the problem:

If you are also getting such error, hope it will helps you to solve the problem.

The above error say we don’t have permission to modify so we tried to give permission as following:

  • Admin >> System >> Users >> User Groups >> Edit the Administrator >> clicked “Select All” for both access permission and modify permission, then clicked save.

With above permission we should be able to get access but still got same errors so we checked the code and found some glitch.

We checked admin\controller\extension\theme\default.php in OpenCart 3.0 and found following permission check at validate() method.

if (!$this->user->hasPermission('modify', 'extension/theme/theme_default')) {
    $this->error['warning'] = $this->language->get('error_permission');

But when we check at the User group permission it is extension/theme/default

So above code need to changed to following:

if (!$this->user->hasPermission('modify', 'extension/theme/default')) {
    $this->error['warning'] = $this->language->get('error_permission');

With this change we are able to save, but still we are not able to retrieve the save theme setting so we checked the code again and found following:

if (isset($this->request->get['store_id']) && ($this->request->server['REQUEST_METHOD'] != 'POST')) {
    $setting_info = $this->model_setting_setting->getSetting('default', $this->request->get['store_id']);

So we changed it to following

if (isset($this->request->get['store_id']) && ($this->request->server['REQUEST_METHOD'] != 'POST')) {
    $setting_info = $this->model_setting_setting->getSetting('theme_default', $this->request->get['store_id']);

Then, it all starts to work.

Enjoy and let us know if you are getting any kind of errors.

  1. Thanks for the Fix i really appreciate your effort but you’ve gone little far you don’t need the code where you’re changing the getsetting module it’s not needed the code will work fine with the permission code but if you edit the getsetting code it’ll not show the changes in the panel but it’ll change them please consider to edit your answer thanks
