Cannot modify header error

The error seemed to have gone away.

I am getting the same error as above when I login to WordPress. Plugin version 1.4 on WordPress 3.6.

In addition, these other errors:
/wp-content/plugins/sucuri-scanner/sucuri.php:360) in /public_html/wp-includes/option.php on line 571

wp-content/plugins/sucuri-scanner/sucuri.php:360) in /public_html/wp-includes/option.php on line 572

Unlike the above user, the “line 625” error has not gone away on my site. The previous version was working fine… until I updated to version 1.4.

Hi there! Are you still experiencing the issue? We are not able to reproduce here.

What other plugins do you have enabled?

Thanks!
Dre

Still doesn’t solve the issue. There’s an update a while ago. Now I ended with another box of error message after the update.

Now all error message is gone.

I updated to version 1.4.1. The “line 625” error disappeared, however, the “line 571” and “line 572” errors appeared on top of the “Last user login” yellow message box right after I updated the plugin.

Strangely, after I logged out and then logged back in to WordPress, the ERROR MESSAGES ALL DISAPPEARED.

I then cleared my browser cache and logged in again. The “line 571” and “line 572” errors again appeared on top of the “Last user login” yellow message box.

It seems that the errors only appear:
1. After updating the plugin.
2. When the user logins to WordPress (and previous login cookie has expired/cleared from browser cache).

OK Im getting the problem as well, but also something new. WP3.6. With version 1.4 I get this error message:

Like the others this error is intermittent, but keeps coming back.

Then after upgrading to 1.4.1 I get a funny box with some code in it, that I can click a cross to close…

This across more than one site, with different plugins. All errors disappear when plugin deactivated, and return when reactivated.

Afraid I’m going to have to shut down your plugin until this is fixed.

I’m getting the modify header errors as well. They only go away when I deactivate this plug-in. So it’s nothing to do with other plug-ins, this one just needs to be fixed. And yes I did update.

Thanks everyone for the input, we’re testing right now to see what’s going on. We’ll update ASAP.

I am getting the same error and I am now unable to login to my client’s site.

Any assistance would be appreciated!

I am listing the entire set of errors (below) in case it helps. I get these by simply navigating to the site’s WP login screen (i.e., /wp-admin) and the WP login box/fields is displayed below this long list of errors:

When I do try to login I simply get the following 3 errors (and then whitespace — no access to my client’s site)…

Warning: Missing argument 2 for sucuri_login_redirect() in /home/content/89/8175589/html/wp-content/plugins/sucuri-scanner/sucuri.php on line 619

I found out I was actually logged in to my client’s WP site when I navigated to the site’s home page. I then deactivated the Sucuri plugin and now can log in and out of the site with no problem.

Here is some additional info I should have included in the above post…
WP version: 3.6
Theme: Atahualpa, current version: 3.7.12
Other plugins installed: (all current versions) Share Buttons by AddToAny, Stop Spammer Registrations Plugin, WordPress Importer, Secure WordPress, and WP Security Scan.

Thanks.

Hey there, the team is looking into it to try and reproduce. By chance did you try disabling all the other plugins to see if the error goes away?

Thanks,
Dre

Sorry, I have not had the time to test by disabling the other plugins. I have highly customized some of then (e.g., stopspammers.) If I deactivate, I will need to reproduce the configurations which will take some time. I’m buried with work today. If your testers are not able to reproduce sooner than later, I will try to make time for it tomorrow.
Cheers,
Bob

I updated to version 1.4.2. The update did not make errors go away. Instead, it introduced a new error that appears on my WordPress login page – /wp-login.php:

Warning: Missing argument 2 for sucuri_login_redirect() in /wp-content/plugins/sucuri-scanner/sucuri.php on line 619

The “line 571” and “line 572” still occur.

The errors only occur after I login (when the WordPress cookie login has expired/been cleared from browser cache). If I logout out and then log back in the same open browser tab, the errors will not appear. But if clear the browser cache, close the browser, re-open the browser and log back in, the errors occur.

OK, I updated now to version 1.4.3. The “line 619” error that was introduced to my blog in version 1.4.2 has now gone away.

However, the “line 571” and “line 572” error messages that were introduced when I updated from 1.3 to 1.4 (1.4.1, 1.4.2, 1.4.3) still persist after I login. I suppose I could live with the errors since they do not appear on the front-end… and they don’t show up all the time. Still… kinda annoying. Hope it gets fixed, otherwise I guess I’ll just revert to version 1.3.
