I get this error while in the Configure Event -> Online Registration tab and trying to enable the Send Confirmation Email feature:
Warning: idn_to_ascii() expects parameter 3 to be integer, string given in /home2/nymissionary/public_html/administrator/components/com_civicrm/civicrm/packages/HTML/QuickForm/Rule/Email.php on line 58
A screenshot is shown below. I need your help so I can use this feature.

It looks like this issue has been reported and fixed here: https://lab.civicrm.org/dev/core/issues/1469
With this patch https://github.com/civicrm/civicrm-packages/pull/271.patch
To apply.
First make up a backup of the file.
Then option one - if you have command line access you would want to
navigate to
/home2/nymissionary/public_html/administrator/components/com_civicrm/civicrm/packages/
Download the patch using wget
wget https://patch-diff.githubusercontent.com/raw/civicrm/civicrm-packages/pull/271.patch
This will create a file called 271.patch
Then you want to apply the patch using the patch command
patch -p1 < 271.patch
( What this does
)
In this case it looks like a pretty simple patch that you could do manually if you were more comfortable.
Again make a backup of the file then edit the file: HTML/QuickForm/Rule/Email.php
Then look at https://patch-diff.githubusercontent.com/raw/civicrm/civicrm-packages/pull/271.patch
What you want to do is add any line (without the +) that starts with a plus and remove anything with a minus.
You want to add the code between the lines without the pluses above and below so the first chunk will go in about line 37.
after
class HTML_QuickForm_Rule_Email extends HTML_QuickForm_Rule {
but before // switching to a better regex as per CRM-40
Then the second bit you just need to swap
$part = idn_to_ascii($part, 0, INTL_IDNA_VARIANT_UTS46); for $part = self::idn_to_ascii($part);
If you get any errors after saving just revert to your backup.
