Welcome the Technical Support section. Help us in assisting you by providing us with a concise and descriptive elaboration of your issues. Be specific and if possible, provide us with a step-by-step instruction in replicating your problem.
"Blocked" means that certain user blocked those kind of emails in his/hers profile email settings.
I assign developer to check that "Undefined error".
- Instead of saying: 'it's not working', explain the problem in detail.
- Screenshots with the URL visible in them and the problem marked are more than welcome.
- Tell us how to replicate the problem, we can't fix it if we can't find it.
- Make sure that your site/server meets JomSocial System Requirements
- Make sure to setup JomSocial Cron Job
- Always provide us with access details to the backend and ftp. We need it to debug problems.
- If you have a similar problem, but a solution you found isn't working, open a new thread instead of 'merging' with an existing one.
- Use the "Thank You" feature on any post that helped you
The block email means the email joomla code cant send the email, it can be caused by overload email on your server. This is not Jomsocial issue but email server is overload, to avoid this please you edit administrator/components/com_community/default.ini and change this value "totalemailpercron" to the smaller value.
If you still get this issue I suggest you contact your sys-admin for this
