Dear Gabriel, thanks for the info, will look for the version 1.3.3.1. And I would like to congratulate you for the great service and also by the plugin, have not used it yet, but it seems to me wonderful. Thank you.
Yes, myCRED folder is in the plugins directory (wp-content/plugins/mycred) and the PHP version is 5.2.17
Same thing happened to me … upgraded to version 4.2.0 and now when I go to settings there is nothing available, only the text of the tabs. I can not insert images in the galleries and do not allow access settings.
