Help with Backend Parse Error!

[Guest]

Any help with this error would be greatly appreciated. I recently installed a contribution and thought that was the cause of this error, but I restored the files to their backed up state and still this error happens. I'm a newbie with PHP so I can't figure out what this means. I get this when in the backend and click on Configuration > Images and then try to Edit 'Product Image Height'.

 

Parse error: parse error, unexpected T_CONSTANT_ENCAPSED_STRING in /home/abc/public_html/admin/configuration.php(125) : eval()'d code on line 1

 

The file configuration.php has not been modified since the original store install.
