Getting a string error when editing the Site Summary Block

[Info 3bits]

Got this error with debugger enabled:

Invalid get_string() identifier: 'region-frnt-footer' or component 'theme_bcu'. Perhaps you are missing $string['region-frnt-footer'] = ''; in /var/www/adaptable/theme/bcu/lang/en/theme_bcu.php?

Invalid get_string() identifier: 'region-frnt-footer' or component 'theme_bootstrapbase'. Perhaps you are missing $string['region-frnt-footer'] = ''; in /var/www/adaptable/theme/bootstrapbase/lang/en/theme_bootstrapbase.php?

It is looking for the string in bcu, bootstrapbase and finally in base and can't find it.

Fixed after reinstall the theme
