Login Issue with Ultimate Member – Incorrect Password Message

Hello everyone,

I’m experiencing a persistent issue with the Ultimate Member plugin on my WordPress site. When users try to log in, they frequently receive an “Incorrect password. Please try again.” message. Here’s a detailed summary of the issue and the steps I’ve already taken to try to resolve it.Issue Overview:

• I’m using Ultimate Member to manage user registrations and logins on my site.
• I added captcha protection (first Google reCAPTCHA and then hCaptcha) to secure the login page from bots.
• However, once any captcha is activated (Google reCAPTCHA or hCaptcha), even after successfully validating the captcha, users receive an “Incorrect password” error, despite entering the correct password.

Troubleshooting Steps Taken So Far:

1. Deactivating Captcha Plugins:
   • When I deactivate all captcha plugins (by renaming their folders), users can log in normally. However, this leaves the registration page vulnerable to bots.
2. Testing Different Captcha Plugins:
   • I’ve tried Google reCAPTCHA v2 and hCaptcha, but the issue persists. Once the captcha is activated, the “Incorrect password” error appears after validation, even when the password is correct.
3. Modifying Ultimate Member’s Login Validation Code:
   • I implemented various solutions from GitHub and support forums, including this GitHub suggestion to replace Ultimate Member’s login authentication function in my theme’s functions.php file.
   • After adding this code, the error message changed from “Incorrect password” to “Captcha not solved”, even when the captcha is correctly validated.
4. Checking for Plugin and Theme Conflicts:
   • I tested by deactivating all other plugins and switching to a default WordPress theme. The issue persists only when captcha is active, indicating a specific conflict between Ultimate Member and the captcha plugins.
5. Researching GitHub and WordPress Forums:
   • After reviewing various discussions, such as this GitHub thread and this WordPress forum post, I tried all suggested solutions, but none have fully resolved the issue.

Current Configuration:

• WordPress: Latest version
• Ultimate Member: Latest version
• Captcha Plugins Tested: Google reCAPTCHA, hCaptcha
• Security Plugins: Deactivated for testing

Any help or suggestions would be greatly appreciated! This ongoing issue is impacting user experience and leaves the site open to bot registrations when captchas are disabled. Any insights into resolving this conflict would be invaluable.
