Thanks @joomdonation ^_^

You're welcome @javigomez . Hopefully this PR can be reviewed and merged (It is quite difficult to provide testing instructions for these kind of PRs :( ).

@Test, I've tested this issue, please find my test cases as screen shots:

This comment was created with the J!Tracker Application at issues.joomla.org/joomla-cms/4651.

Thanks @rajeshstarlite for testing this PR. Unfortunately, I deleted the original repo and now I could not update the PR with new code. Could you please help making another change and test it again:

1. Open the file components/com_tags/views/tags/view.feed.php

2. Find the code below:

$feeditem->link        = '/index.php?option=com_tags&view=tag&id=' . (int) $item->id;

1. Change it to:

$feeditem->link        = JRoute::_('index.php?option=com_tags&view=tag&id=' . (int) $item->id);

After that, please help test it again. If everything goes well, I will open a new PR to fix this issue.

For some reason, I could not see the author displayed as well. Maybe it depends on the rss reader which we are using. If you view the source of the feed, you will see the is generated like below (the author tag is available but not displayed)

<item>
<title>Components</title>
<link>http://localhost/jcms/index.php?option=com_tags&amp;view=tag&amp;id=2&amp;Itemid=582</link>
<guid isPermaLink="true">http://localhost/jcms/index.php?option=com_tags&amp;view=tag&amp;id=2&amp;Itemid=582</guid>

Sorry for could not reply you earlier. It was my office time, so I could not work on it until now (after dinner :) )

Thanks again

@Hackwar @wilsonge I created a new pull request #5552 to replace this one (because I deleted the original repo and don't know how I can edit code without it). Please help checking the new PR when you have some time.
