Hm, when you cancel your site SSL support? I suspect all this while the issue is coming from this because I remember last month or last few week we are still can able to accessing with your https site.

If you already cancel your SSL support and I think you have to double check on your site and see which part is still configure to use https protocol.

Come back to your issue, can you try turn on error reporting to maximum from backend global configuration page, then run this URL again on your browser and see what is the exact PHP error it show?

https://www.conexionswinger.com/index.php?option=com_easysocial&cron=true
https://conexionswinger.com/index.php?option=com_easysocial&cron=true

And finally I tried to use your guide but I don't understand it well, where does "http://site.com/index.php?option=com_easysocial&crondata=true";; go?

If you do not have allow user to request download their own personal data on your site, you do not need to setup this.

If you allow user to request download their own personal data, then you can add another new cronjob command on your cronjob configuration on your server.

Add this :

/usr/bin/wget -O /dev/null "http://www.conexionswinger.com/index.php?option=com_easysocial&crondata=true"

And set your both cron command cron interval to 3 minutes.

By the way, we still unable to access your site.

Apparently if I have the SSL Certificates, as in the attached screen.
You can access the CPANEL please

Access to my CPANEL is: https://conexionswinger.com:2083/

Activate the error report to the maximum and the following appears:

With this URL:
https://www.conexionswinger.com/index.php?option=com_easysocial&cron=true
keeps getting ERR_TOO_MANY_REDIRECTS

But with this other one: https://conexionswinger.com/index.php?option=com_easysocial&cron=true

Currently we can't access your site at all even your Cpanel

Can you increase your PHP memory_limit to 512M and see how it goes?

Also can you send us 1 screenshot about your remote storage setting from backend > Easysocial > setting > storage ? I would like to see whether you have setup Amazon S3 on your site.
