Unsubscribing from comment notifications

[cristitm]

Hello and thank you for this great component!
If a user wants to be notified about follow up comments and then tries to unsubscribe by clicking the "unsubscribe" link that he receives into his e-mail, nothing happens. The "unsubscribe" link is actually not a link, so is not clickable.
Any help will be much appreciated.

Hi
I have a similar problem (look at the topic below yours) - I get an error 500 when click "Unsubscribe".
As far as I understood, this is something to do with the URL forming - there is some mistake in it. Probably it lacks the words "view=html" but I'm not sure.
Let's wait for the experts - their opinion is extremely needed.

JComments and Joomla version? Do you use any 3rd party SEF extension? In case of 500 error - could you check your server's error.log and find  there some information about error?

Hi,
Thanks for your reply.
What I see in error.log file:

PHP Parse error:  syntax error, unexpected T_STRING in /.../components/com_jcomments/jcomments.class.php on line 1741

which is strange because line 1741 contains only "{" - please find the code piece below.

If it matters, I use a standard SEF, included in Joomla.

Code:

1740 public static function getLink($type = 'ajax', $object_id = 0, $object_group = '', $lang = '')
1741 {
1742 global $iso_client_lang;
1743
1744 $app = JCommentsFactory::getApplication();
1745 $config = JCommentsFactory::getConfig();
1746
1747 switch($type)
1748 {
1749 case 'rss':
1750 if (JCOMMENTS_JVERSION == '1.0') {
1751 return $app->getCfg('live_site') . '/index2.php?option=com_jcomments&task=rss&object_id='.$object_id.'&object_group='.$object_group.'&no_html=1';
1752 } else {
1753 $link = 'index.php?option=com_jcomments&task=rss&object_id='.$object_id.'&object_group='.$object_group.'&format=raw';
1754 if ($app->isAdmin()) {
1755 $link = JURI::root(true).'/'.$link;
1756 } else {
1757 $link = JRoute::_($link);
1758 }
1759 return $link;

Hi,
Thanks for your reply.
What I see in error.log file:

PHP Parse error:  syntax error, unexpected T_STRING in /.../components/com_jcomments/jcomments.class.php on line 1741

Original file jcomments.class.php has no syntax errors. It's looks like you've changed some code. I suggest you to reinstall component.

[iglinatv]

Hi,
I already reinstalled it several times and it is still not working. Now errors are not recorded in the error.log file (no new records in it). But 500 error keeps showing.
What should I do?

[smart]

If error 500 appears then something must be logged in error.log...

[iglinatv]

Just checked again - no new records in error.log but the error persists.

Could you please check the look of the unsubcribe URL? My link looks like the following:

administrator/index.php?option=com_jcomments&task=unsubscribe&hash=081cae69bde469dffb40e66f66c62471&format=raw

Probably, there is some mistake in it.

Thanks!

[smart]

It looks like correct link... Could you check your PHP.INI settings - may be display_errors set to off? Or try to set more detailed error reporting's level in Joomla configuration. It is very strange - you got 500 error and empty error.log.


BTW, I see you've email on yandex.ru - if you want you can use russian in our communication.
