Hi Roger,
Thank you for reporting this issue.
Could you please provide a few screenshots showing the email notification settings, the text you are trying to change, and the red X message that appears after clicking Save? This will help us better understand what is happening.
Could you please share temporary administrator access to your Joomla backend? You can provide the credentials securely in the hidden content section. Also, please take a full backup of your site before we make any changes.
Once I have access and screenshots of the issues, I’ll investigate further and see what’s causing the issue. Let me know once you’ve shared the details!
Best regards,
Thank you!
