Are you encountering the frustrating 403 admin-ajax.php error while trying to upload images through WPDevArt Gallery uploader? Here's a swift solution to get you back on track:
Access your cPanel dashboard.
Navigate to the "Security" category and locate "modSecurity."
Temporarily disable modSecurity (but don't forget to re-enable it once your uploads are complete!).
Give uploading another shot, and voilà! Enjoy your hassle-free experience.
Keep in mind to reactivate modSecurity once you've finished uploading your images. Happy uploading!
