I am getting these errors when logging in:

Warning: Missing argument 2 for Connections_Link::processLinkOnLogin() in /home/abng/public_html/wp-content/plugins/connections-link/connections_link.php on line 694

Warning: Cannot modify header information – headers already sent by (output started at /home/abng/public_html/wp-content/plugins/connections-link/connections_link.php:694) in /home/abng/public_html/wp-includes/pluggable.php on line 1179

Any ideas?

And it started recently.

My first guess is that you’re using an older version of Link. Can you first try updating Link to the latest version?

If that doesn’t fix it and since “it started recently” that hints to the possibility of a new plugin that was installed or a plugin update that is breaking the hook in WordPress Link hooks into to properly function. Which plugins have you installed or updated recently, try deactivating them to see if the error goes away.

I have been updating the plugins as often as possible. It doesn’t look like link has been updated since July…correct?

re: I have been updating the plugins as often as possible. It doesn’t look like link has been updated since July…correct?
Right, the latest version is 2.0.2. Do you have version 2.0.2 installed?

What about my second comment? “since “it started recently” that hints to the possibility of a new plugin that was installed or a plugin update that is breaking the hook in WordPress Link hooks into to properly function. Which plugins have you installed or updated recently, try deactivating them to see if the error goes away.”

Have you temporarily deactivate other plugins to see if the error goes away? My guess is another plugin or maybe even the theme is improperly hooking into the WordPress wp_login action hook.

I do have 2.0.2 installed.
I have a feeling it is “Pie Register” that is causing the issue. But, I need to charge people to access the site and Pie Register does a great job.

I had “User Switching” enabled and that caused a few errors too. But deactivating that worked for a few of the errors.

Well, I know “User Switching” works perfectly fine with Connections and Link … I use it, a lot, myself.

My vote is “Pie Register” … I’m checking out its code right now …

@ Ben

Yep, it’s “Pie Register”. They quite possible broke any plugin that relies on the wp_login action hook.

Here’s the lines of code that has the bug:
– https://plugins.trac.wordpress.org/browser/pie-register/tags/2.0.13/pie-register.php#L966
– https://plugins.trac.wordpress.org/browser/pie-register/tags/2.0.13/pie-register.php#L1001
– https://plugins.trac.wordpress.org/browser/pie-register/tags/2.0.13/pie-register.php#L1014

They should either not call the wp_login action hook at all or they should pass the $user object as a second variable like so:
do_action( 'wp_login', $user->user_login, $user );

The only fix right now … You’d have to edit that file, all three instances, to either remove the call or add the second variable. The safest solution is the latter because it might be possible that “Pie Register” may run in a way the core WordPress action wp_login is never run and it needs to run for Link and any other plugin that may rely on it.

Hope that helps!

[Ben Winter]

Thanks for the troubleshooting. I will reach out to their team and see if they can provide a fix.

If you have a moment, I would truly appreciate a review as they really do make a difference. Many thanks in advance!
