Failed to Save Changes in RankMath SEO Settings

Hello RankMath Support Team, I’m encountering a specific issue with RankMath on my website (https://vatcalculator-ireland.com/) that I need assistance with. When I attempt to save my SEO settings, especially under the “Titles & Meta” section, I receive the error message: “Error: Failed to save changes. Please try again.” This issue prevents me from updating important SEO information for my website. I have already tried deactivating and reactivating the RankMath plugin, clearing my browser cache and cookies, checking for plugin conflicts by disabling other plugins, switching to the default WordPress theme (Twenty Twenty-Three), and verifying user permissions in WordPress, but the error persists. My website is hosted on SiteGround, and I am using WordPress version 6.3.1, RankMath version 1.0.110, and PHP version 8.0. I would appreciate any guidance or troubleshooting steps that could help resolve this issue. If there are any logs or error traces that could shed light on the cause, I would be happy to provide them. Thank you for your support.
