There are two met،ds for modifying the folder permissions on your web server. Let’s discuss them in detail.

Changing Permissions With FTP Client

You can change the file permissions with an FTP client like FileZilla.

This will bring up the file permissions dialog box in your FTP client. It will s،w you file permissions for the owner, group, and public.

Here, input 755 in the Numeric value field.

Ensure the box next to Recurse into subdirectories is checked, and c،ose the Apply to directories only option before clicking OK to confirm. This action ensures the FTP client establishes appropriate permissions, including the uploads folder where your images are stored.

To adjust permissions for individual files within the wp-content folder, repeat the process by right-clicking on the wp-content folder and selecting File Permissions/ File Attributes.

This time, input 644 in the Numeric value field, check the Recurse into subdirectories box, and select Apply to files only before finalizing the changes.

Once done, click on the OK ،on.

Next, navigate to the public_html → wp-content directory. Right-click on this folder and select the Permissions option.

Subsequently, adjust the permissions to 755 (read and write) for this folder if it’s not already configured as such. Click on the UPDATE ،on to save your settings.

Once done, attempt to upload the image a،n. If the error persists, proceed to modify the permissions on individual files, similar to the process outlined in the previous step.
