Can't login

When you try to login, what happens exactly?

Nothing happens, i just can’t login, keep getting this error no matter how many times i try.

The system logged me out to “wp-login.php?wpsf-forcelogout=4” immediately when i clicked “Activate plugin” after install. Then it won’t let me login until i deleted this plugin.

Yep, I get that. Are you saying that with the plugin activated, each time you click the login form to login, you get the message:
“You do not currently have a Shield user session. Please login again.”
?

What all plugins have you got running? Have you tried an alternative WordPress theme?

Like a said, i installed fresh WordPress and right after that i installed your plugin… Okay here is the steps:
1. Installed WordPress.
2. Immediately installed Shield.
3. Clicked “Activate Plugin”.
4. Kicked out to login page with “You do not currently have a Shield user session. Please login again.” error.
5. Entered my login and password then clicked “Log in”.
6. See step 4.

It’s possible that the necessary database table wasn’t created correctly, or it’s corrupt.

Are there error_log files in your hosting directory? If so, is there any mention of the plugin in there pertaining to user_management database table?

I have a record in my error.log of Apache:

PHP Warning:  setcookie() expects parameter 3 to be integer, float given in ...\wp-content\\plugins\\wp-simple-firewall\\src\\common\\icwp-data.php on line 710, referer: .../wp-login.php?wpsf-forcelogout=4

hmm… that could be the root cause. Are you running php 7?
This has come up elsewhere last week and I have a patch waiting. Could you download the raw contents of this file:
https://github.com/FernleafSystems/Shield/blob/develop/src/common/icwp-data.php

…and replace what you have on your server? This should fix the variable type issue and hopefully the underlying cause of this whole problem.

Yes, i’m using php7 and looks like this new file fixed the issue, thank you.

Brilliant! Thanks for testing. I’ll release the final fix tomorrow.

Hi, I’m facing a similar problem on a fresh install.

Each time I activate a plugin, I’m taken to /wp-login.php?wpsf-forcelogout=4

The strange thing is that I get two alerts:

“It appears you’re already logged-in.
Go To Admin →”

and

“You do not currently have a Shield user session.
Please login again.”

If i click Go To Admin then I can see I’m already logged.

Very annoying.

PHP5

do you have any other plugin pertaining to users, security, login, sessions?

Hi Paul. It seems that today the problem has gone away. Can’t figure out why as I’ve already flushed browser cache yesterday, and it still behaved strangely… however, it works fine now. It may have been some automatic hosting-related caching issue.
