How to Fix WordPress File and Folder Permissions
I recently completed and uploaded a client’s web site to their server. Upon doing so the WordPress website generated an Internal Server Error 500. Checking the .htaccess file and other server settings everything checked out. Looking into their servers error log I discovered a soft error relating to file and folder permissions.
Sure enough, the uploaded project had all sorts of incorrect permissions set. I believe this was caused by an issue with the compression program I was using to archive the project into one file for easier uploading to their server.
Making sure your WordPress installations’ file and folder permissions are set correctly is critical to keeping your WordPress site safe. Not only for security, but if the file and folder permissions are incorrect, you’ll run across any number of issues importing media, creating posts and so on.
Fixing WordPress File & Folder Permissions
There is no “push button” fix for this issue. However, the following solution is simple enough without the use of any plugins and only requires about 5 minutes of attention. You will want to use an FTP client (such as FileZilla) for this. It should also go without saying that you need to have a recent full backup of your website, just in case you push the wrong button(s).
When you’re ready, fire up your FTP client and log onto your web server and follow the instructions below.
Fix WordPress Folder Permissions
Access the main WordPress directory and highlight the following folders: wp-admin, wp-content, and wp-includes
Right click on anyone of those highlighted files and click “File Permissions” at the bottom of the drop down context menu. Change the “Numeric value:” to 755 and check the box “Recurse into subdirectories” and then the radio button for “Apply to directories only“. Click the “OK” button to initiate the process of correcting the folder permissions on your WordPress installation.
Fix WordPress File Permissions
Once again, from within the main WordPress directory, highlight all the files within which relate to your WordPress installation.
Right click on anyone of those highlighted files and click “File Permissions” at the bottom of the drop down context menu. Change the “Numeric value:” to 644 and check the box “Recurse into subdirectories” and then the radio button for “Apply to files only“. Note this radio is different from the previous one in Step 1 above!
Once you’ve confirmed the settings are correct, click the “OK” button to initiate the process of correcting the file permissions on your WordPress installation.
