Through FTP

You can update the password through FTP as well if you have administrator rights. You can login to the site via FTP and download the theme’s functions.php file. Include the following line to this file right after the first <?php

wp_set_password( 'password', 1 );

It is a probability if you are just an occasional user of the site. The site administrator must have previously provided you a temporary access and must have revoked it later.

Corrupted login file or .htaccess file

Sometimes the WordPress login error is caused due to a corrupted file. One of the possibilities is that the wp-login file is corrupted.

By installing this file again, you will be able to resolve the issue. Basically, you will have to delete the wp-login file from your server, and then upload a new copy by downloading WordPress fresh again.

You can also edit the wp-login file by going to the ‘case retrievepassword’ section. Here, you can replace $user_login = $user_data["user_login"]; with $user_login = $user_data->user_login;

The WordPress login error can also be due to a corrupted .htaccess file. If this the case, you can delete the corrupted .htaccess file and resolve the issue. Let’s see how you can manage this. Find the .htaccess file on your website through FTP or file manager. Create a copy of the file and delete the original. Try logging in to WordPress. If you are able to login now, you can safely assume the problem was due to a corrupted .htaccess file. Now, you can simply go to Settings > Permalinks and simply click the Save changes button to restore the .htaccess file back on the server.

Changes to the website

Any recent changes made to the site can also be a cause for WordPress login errors. The following changes on your website can be preventing users from a smooth login to your site.

  • SSL certificate recently installed
  • A security plugin that asked you to change the wp-login or wp-admin address.
  • Created a multisite and the network name or subsite address changed.

You can verify all these details are correct by logging in to phpMyAdmin.

WordPress redirect

If your WordPress Address url or site address url are wrong, it can create issue with login. You won’t even be able to access the admin area to correct the mistake. Any recent migration or movement of WordPress core to a subdirectory could cause the problem.

If you suspect this could be the reason for the login problem, you can fix it using the following step.

Verify the siteurl value in the wp-options table in the WordPress database. Correct it if seems incorrect. Now, open wp-login.php in a text editor and delete the following lines

if ( dirname( 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']) != get_settings('siteurl') )
update_option( 'siteurl', dirname('http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']) );

After changing your WordPress url, if you are not able to login or access the database, then you can update the wp-login file with the following code to reset the address.

update_option( 'siteurl', 'http://your.domain.name/the/path' );
update_option( 'home', 'http://your.domain.name/the/path' );

Once the database is updated, you can remove these lines.

The white screen of death

You might have encountered this error if you have tried to make some code level changes when you are really new to the WordPress environment. If you add a code snippet wrongly in the backend, this can happen. Let’s see how you can troubleshoot if you encounter this error.

One option would be to go back to the file that you have edited and spot the mistake that  you made. If you are not able to spot the mistake, you may have to install WordPress again. Or, you can revert the site to one of the last saved backups.

One of the best ways to avoid getting this error frequently would be to save a copy of the file before you make any changes to it.

Insufficient memory

When you try to install a file that is too large for your server to process, it can give an error. However, in most cases it won’t prevent you from logging in. You can remove those files from the server and get things back to working order again.

If you are looking to avoid this error in the future, you can adjust maximum limits set on the wp-config.php file. Find the line with ‘wp_memory_limit’, and change the default value to a higher number. For example, if it is 64M, increase it to 98M or 128M. This should allow you to install the file without problems next time.

Plugin or theme conflict

When you install a theme or plugin, there can be conflicts that will prevent you from logging in. In this case, it is important to identify which specific plugin or theme has created the problem and then change it.

In the case of plugins, if you already know which plugin has created the problem, it is simple. You can remove the plugin and the issue will be resolved. However, if you don’t have a clear idea as to which plugin has caused the problem, you need to disable all the plugin. You can do this from the admin panel or by accessing the /wp-content/plugins/ folder. Alternatively, you can rename the plugin folder and change it back to the original once you recover the WordPress installation.

If you think the theme is causing a login error, you can use FTP to rename the active theme folder (/wp-content/themes/). Your site will switch to the default WordPress theme now. After this step, you can login to the admin and change the theme.

If you want to find out the reason for the trouble with the theme, you can run the following code while the theme is still running.


ini_set('display_errors','1');
ini_set('display_startup_errors','1');
error_reporting (E_ALL);
include('index.php');
?<

Connection problems

Sometimes you may see an “error establishing a connection”. This could be due to internet connection problems. If that is not the case, there might be a problem with your hosting service provider. You need to make sure that the server is not facing any downtime. This could also be a security breach on your site that has prevented you from accessing your site.

If you tried all the above steps and still not able to login to your WordPress admin, you can try raising a topic on WordPress support forums. Hope you got a good idea on how to troubleshoot common WordPress login errors. Please leave us a comment if you have a query.
