Parse error: syntax error, unexpected T_CLASS

I wanted to make some changes in the class-main-footer.php file. After I clicked ‘update’ I saw this:

Parse error: syntax error, unexpected T_CLASS in /home/content/37/10654937/html/wp-content/themes/customizr/parts/class-main-footer.php on line 1

I downloaded the theme again and copy-pasted the class-main-footer.php file directly into the corrupted file via FTP (FileZilla).

Is there anyone who can help me with this? Thanks a lot in advance.
