Apologies for the delay in our response. We have recently retired the ALM service. It was an experimental service, and will not be revived in its current form. I would recommend that you disable the plugin that displays that broken image.
OJS 3 can display usage statistics without requiring an additional plugin or service - see this blog post on the subject. We don't expect that this functionality will be back-ported to OJS 2, and we will continue to improve the metrics and display options in OJS 3, and so I would recommend upgrading if that is an option for you.
