[Closed] Fatal Error on rank math Sitemap page

Hello There,
Thanks for contacting WPML Support.

I understand the issue you're having and will try my best to assist you in this matter. Based on the error log, this issue most of the time happens due to incomplete setup of the Admin profile, specifically when the First Name and Last Name fields are left empty or if the Email format is incorrect. Could you please try the following steps to see if they resolve the problem?

1. Navigate to "Users > Profile" and make sure you've correctly entered your First and Last name in the Profile section.
2. Next, go to "WPML > Translation Management > Translator."
3. If you've already added your profile as a translator, please remove it and then re-add it. If you haven't configured the Translator yet, you can leave it as it is.

Please check and let me know if that helps to solve the issue or if you need further assistance in this matter. I will be happy to help.

Best regards,
Prosenjit

Hi There,
Thank you for the update.

Could you please confirm if there are multiple translators on your site? If that's the case, could you also verify whether their profiles have been properly set up with a First Name and Last Name? If everything appears correctly configured, try removing the translators and then re-adding them to see if the issue persists.

If this issue occurs randomly, please also check by clearing the caches. If caching is enabled at the server or hosting level, ensure to clear those caches too, and then reevaluate the situation.

Let me know the update. I will be happy to help if you need further assistance in this matter.

Best regards,

Hello There,
I hope you're doing well. Sorry for the delay in responding due to the weekend.

Thank you for the update. I'd like to inform you that the Rankmath and WPML SEO plugins are compatible, and we haven't received any recent reports of issues between them. Given that the fatal error started to show after the WPML SEO Plugin was installed, please try the following steps to see if they resolve the issue:

- Ensure your site has the latest versions of the WPML, String Translation, and Rank Math plugins installed.

- Deactivate the WPML SEO plugin, then remove it from your WordPress site.

- Download a new WPML SEO plugin from https://wpml.org/account/downloads/, install it, and activate it on your site.

- Verify whether the fatal error still appears on the Sitemap page. If the problem continues, try deactivating all plugins that are not related to WPML and Rank Math SEO to determine if this resolves the issue.

- Conduct a test with one of the default themes to see if the issue persists.

Please remember to back up your database before making any changes.

Please let me know the update. In case you need further assistance, I will be happy to take a closer look and assist you accordingly.

Best regards,
Prosenjit
