Hi @morisalisa,

It seems that you have an old version of the Cera theme (1.0.1).

We recently release a new version (1.0.3) of your theme. Updating your theme and all the required plugins to the latest version should fix these two issues.

If you have correctly updated the theme and Grimlock, the problem should now be fixed. You might still be seeing the issue because your browser cache is showing you an older version of the page (browsers do that to load pages faster). So to see that the issue is resolved you will need to empty your browser cache and reload the page. If you want to read more on what browser cache is and how to clear it, here is an article that might help you:

To update your theme, you can download and install the Envato Market plugin (https://envato.com/market-plugin/) on your WordPress site.

Once the plugin is installed and activated, go to “Envato Market” in your admin menu and follow the instructions under “Activate Envato API Connection”.

When this is done, you will see your purchased themes under the “Themes” tab and you should be able to update your theme from there by clicking the “Update available” button.

Regards
