I checked again the server logs, and I can confirm that the cron executes, however if you receive an email this means that there is something wrong with the script itself.
When opening the URL via a browser: http://mifitnessysalud.com/es/?option=com_easysocial&cron=1 I get a pop-up to download the json file which doesn't seem right.
I will advise you to check this component and see if there is a setting to edit the export to another format and not the json one, or see if there are any other settings that can be causing the issue.
