Hello, thank you very much for your help.
I found removed the text, but the inscription on my site remained.
$calledClass = get_called_class();
if( $functionName == 'theme_core_front_global_footer' or ( $functionName == 'footer' and $app == 'core' and $location == 'front' and $group == 'global' ) )
{
$content = $content . "\n<p id='elCopyright'>
<span id='elCopyright_userLine'>{lang=\"copyright_line_value\"}</span>
$calledClass = get_called_class();
if( $functionName == 'theme_core_front_global_footer' or ( $functionName == 'footer' and $app == 'core' and $location == 'front' and $group == 'global' ) )
{
$content = $content . "\n<p id='elCopyright'>
<span id='elCopyright_userLine'>{lang=\"copyright_line_value\"}</span>
<a rel='nofollow' title='Community Software by Invision Power Services, Inc.' href='https://www.invisionpower.com/'>Community Software by Invision Power Services, Inc.</a></p>";
}
</p>";
}
I removed it but has no effect.
