Hi, Gabriela.

Thank you for contacting us.
JomSocial doesn't control Joomla! mailing function so it's rather can't be caused by JS.
Please, check Joomla! email settings and if you're using PHPmailer function - check if it's enabled on your server.

Hi
Michael - but yesterday they was working fine - and nobody have not changed the setting.
And server is setuped fine - there is no reason to chek - as i`m sure more than 1000 % as is fine - i just don`t understand how cold happening once upgrade component - to get this kind of issue.

i`m a little bit shoked if frankly ...

Regards
Carolina

Hi, Gabriela.

I think it's rather coincident that it stopped working after you upgraded JomSocial.
JomSocial doesn't control or have influence on Joomla! emailing function.
I've checked and I could confirm that you use PHPmailer server function.

Please, browse to Backend -> System -> Global configuration -> Server -> Mail settings and click "Send test email". You'll get: "Could not instantiate mail function." error. Please, read more about this error and what cause it.

If you still insist it's caused by JomSocial do a test - restore your backup BEFORE JomSocial upgrade and check if this issue is solved.

But I think that easier way will be to change from PHPmailer to SMTP.

Hi
I don`t inssist i know sure as this was happened - here is only logical think - if there was nothing done meanwhile.

Ok
I will create an subdomain - and will install on the yesterday backup - and will show to you too - if you don`t beleve.
There the message was come - as can not initiate mail function - but the mails was coming normaly - and the test was reaching normaly.

In 30 min i will rise up the backup.

Hi, Gabriela.

It's not that I don't believe you... I'm just trying to say that this could be a coincident. Maybe that in the same time your hosting did something (upgraded? disabled?) libraries on your server.

"Could not instantiate mail function." notice indicates issues with emailing function in Joomla! Even JomSocial uses Joomla!emailing function (as can't do that on its own... it's Joomla! extension after all). Installing anything in Joomla! couldn't have influence on your server libraries.

But of course I'll wait to test it on your backup site.
