Upload: Failed to Write File to Disk error in WordPress

There can be numerous reasons behind this error but the most common reason is incorrect folder permissions.

Incorrect permissions to folders take away your ability to write files on the server. This means you cannot create, edit or add new files to the folder(s).

If you try to upload images on the server, incorrect file permissions may also produce these error messages

• WordPress failed to write to disk
• WordPress has failed to upload due to an error failed to write file to disk
• Unable to create directory wp-content/uploads/2017/09. Is its parent directory writable by the server?

Solution for Write failed to disk error

The only solution to this problem is to fix the write permission.

You can fix the folder permission error using FTP.

Fix permissions using FTP

Connect to your hosting using FTP client. We prefer using Filezilla.

Once connected, reach to public_html folder.

Search for wp-content folder, right click on them and select file permissions.

Enter 755 in the numeric value field.

Check the box next to ‘Recurse into subdirectories’.

Next click on ‘Apply to directories only’ option.

Click on the OK button to continue.

Your folder permission is set to 755. Now refresh your browser and again try uploading.

WordPress Keeps Logging Out Problem

That can look strange, you continuously keep logging out of WordPress. One of the suspicions can be that someone else is using your credentials.

This is not the case often, it can happen because of URL mismatch in cookies.

Whenever you authenticate admin dashboard on your website, WordPress automatically creates a cookie in your browser. The cookie stored has all the configured settings stored in it, including WordPress URL.

If the URL you are trying to access is different from stored URL, WordPress will not authenticate you and will log you out.

Solution for session logging out in WordPress

A simple fix for this login issue is to make sure that you have the same URL in your Site Address and WordPress Address fields in your WordPress settings.

You can either choose www or non-www in for both the fields.

To change it, login to WordPress dashboard and go to Settings » General.

If you do not have access to dashboard, then change access URL from wp-config.php.

Open wp-config.php and add these lines.

define(‘WP_HOME’,’http://sitename.com’);

define(‘WP_SITEURL’,’http://sitename.com’);

Other Methods

If your URL is same and this error still persists, then try doing these solutions.

• Deactivate all the Plugins
• Clear all browser cookies
• Empty browser cache

WordPress login page refreshing/redirecting issue.

It is another type of login error which most of the user’s face. Your login page keeps refreshing and redirecting back to login screen.   

Most of the time it happens due to incorrect values of site URL in WordPress Options table. It can also be caused because of poorly configured permalink and redirects setup.

Solution for WordPress login page redirecting/refreshing

At first, clear your browser cookies to try resolving this issue. If the issue still persists then try other methods.

Deactivate all the plugins. Sometimes it happens because of two plugins conflicting with each other.

To deactivate simply navigate to /wp-content/plugins/ directory using FTP client or Cpanel’s file manager and rename the plugin folder to plugin_old.

This will deactivate all the plugins.

Update Site URL if plugins is not the issue. To update URL, edit wp-config.php file and add these entries to it.

define(‘WP_HOME’,’http://yoursitename.com’);

define(‘WP_SITEURL’,’http://yoursitename.com‘);

Invisible text and missing buttons in WordPress Visual Editor

This error is quite rare but leave users in astonishment.

In this error your visual editor shows no content or no editing icons for posts or page while editing.

Even if there is text or you are writing something, the writing space will appear white.

This error occurs when concatenated Javascript stops working. Other reasons can be missing or corrupted TinyMCE files or conflict with other WordPress page editor plugins.

Solution for Invisible text and missing buttons in WordPress Visual Editor

Clear browser Cache: The first thing you should do is clear your browser cache or use another browser. This fix has worked for most the the users, so try doing it first.

If this does not fix your issue, maybe the issue is with the scripts.

Replacing TinyMCE Scripts: Download tiny MCE from tinymce.com and replace it with a folder at  /wp-includes/js/tinymce/.

Disable Concatenate Scripts: If none of these worked for you, then disable concatenate scripts from wp-config.php.
Add this line after opening PHP tag.

define(‘CONCATENATE_SCRIPTS’, false);
