Dear Fulgen,

You tick off the default value checkbox in the system setting 'Show configuration version'  to hide the version number http://prntscr.com/nadvom  After that, log out and log in into the system to apply the changes.

Best regards,

Dean

Dean Parrett,

Thanks Dean for your reply

Under system settings i didn't found the suggested option 

'Show configuration version'.

By the way i am using 7.13 version

Fulgen Ninofranco,

You can remove the version number by the means of development. To do so, create a replacing client module for MainHeaderSchema. Override the 

_initConfigurationVersion method, so it returns no value, or override the init method, so it won't call _initConfigurationVersion method. As an additional option, you can create a new CSS module to hide version by the means of CSS. 

Regards,

Anastasia
