Dear Support Team,

I am experiencing a compatibility issue between the Ultimate Member plugin and the WP-Stateless plugin on my WordPress site.

Issue:
When WP-Stateless is activated in Stateless Mode, users cannot upload a profile photo using the Ultimate Member profile editor. The upload dialog appears, but the "Apply" button remains inactive, preventing the photo from being saved. When I deactivate WP-Stateless, the upload works without issues.

Environment Details:

• WordPress Version: 6.7.1
• Ultimate Member Version: 2.9.1
• WP-Stateless Version: 4.1.2
• WP-Stateless Mode: Stateless
• Hosting: Google Cloud

Troubleshooting Done:

1. I confirmed the issue is resolved when WP-Stateless is deactivated.
2. I did not test other WP-Stateless modes (e.g., CDN, Backup) because I am concerned about potential performance decreases. However, I can test these if necessary.

Could you please assist me with resolving this issue? I would like to maintain performance and the benefits of Stateless Mode while ensuring Ultimate Member’s functionality works as expected.

Looking forward to your guidance.

Best regards,
Ibrahem Elzalabany
