what i have to do?

Since these errors are caused since an installation of an extension, contact the theme and the extension developer to resolve this issue. Also ensure your database has been created with the utf8_general_ci .

thank you for your answer

I send ticket to them but they don't answer me

i use utf-8-general-ci in my database

what can i do?

Does the same error message occurs when you uninstall the extensions?

Hi,

can you help me?

If the extension is the caused of this issue and the extension developer does not respond and the downloaded extension was done from opencart.com, contact the Opencart site support to resolve this issue.
