The website cannot display the page

Question

First post on here.

I am a developer for the company I work for and we have a word press site that is public (we host it). For this query lets say the url is http://mywordpresssite

We have just copied the site internally to our DEV server so we can perform development on it. The mySQL database has been copied as well and if I browse to the internal URL I can view the page. Lets say the url is http://mywpsite.

The problem comes when I try to access the admin console on the dev site. On the public site I would use http://mywordpresssite/wp-login.php and this works fine. If I use http://mywpsite/wp-login.php I get the following web page.

I am not that familiar with word press, does anyone have any tips on how to resolve this or where I should be looking to change files etc.

Thanks

UPDATE

I am still having an issue with this but I am a bit further through identifying the issue.

I enabled error logging on the site and when I try to navigate to the admin page the error log displays the following:

[04-Apr-2017 07:31:22 UTC] PHP Warning: Illegal string offset 'remember' in D:\mywordpressstie\wp-includes\user.php on line 39 [04-Apr-2017 07:31:22 UTC] PHP Warning: Cannot assign an empty string to a string offset in D:\mywordpressstie\wp-includes\user.php on line 39 [04-Apr-2017 07:31:22 UTC] PHP Warning: Illegal string offset 'user_login' in D:\mywordpressstie\wp-includes\user.php on line 54 [04-Apr-2017 07:31:22 UTC] PHP Fatal error: Uncaught Error: Cannot create references to/from string offsets in D:\mywordpressstie\wp-includes\user.php:54 Stack trace:

I have been googling it but my php/wordpress knowledge is limited. I found the following URL link to patch, bit no idea how to use this.

Can anyone help?

Answer 1

I fixed it!!! Woohoo.

Using this link - link to patch

I edited the line it advises and it works fine.

Answer 2

There seems to be an issue with the WordPress version.

https://core.trac.wordpress.org/attachment/ticket/37071/fix-wp-login-error.patch

I fixed this by patching the wp-login.php file.

Line 793:
    - $user = wp_signon( '', $secure_cookie );
    + $user = wp_signon( array(), $secure_cookie );

If you copy everything from the actual site, you probably need to check the following:

1. Check wp-config.php to make sure that the host, database credential is consistent to the local database setup;
2. Make sure the wordpress directories are belong to the correct owner. Try sudo chown -R www-data:, replace www-data with whoever owner that have the access for web page;
3. Make sure the directories have the correct access permissions, you can find further information here

If you still have problem, edit your post and provide update.

Answer 4

It seems that your site migration might have missed some steps. Since you mention that you are able to access the home page that means that you have changed the wp-config.php with your local db details.

Did you update the wp-options table ? The table contains two important rows which specify the site and home URL.

You can find more about Moving Wordpress site : https://codex.wordpress.org/Moving_WordPress. You can cross check to see if you missed any steps while migrating.

If you are using a mac for your local dev site - you find detailed explanation : http://egalo.com/2012/05/15/clone-live-wordpress-to-local-env/

Also please check if you have copied live site's .htaccess over to dev - they might contain some re-write rules - which will not work on dev. You might want to rename the file to see if it is the cause of this problem.

Answer 5

I got this error after installing wordpress with composer

Edited the user.php in \plugin-wordpress\wp\wp-includes\user.php

Changed the following lines from

function wp_signon( $credentials = array(), $secure_cookie = '' ) {
}

to:

This solved the error and a wordpress login form entry shows up.

function wp_signon() {
     $credentials = array(); $secure_cookie = '' ;
}
