Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Please avoid sharing the credentials on the body of your ticket to prevent unauthorized access. I have edited your post and entered the credentials on the sensitive data section.
The error reported on the post sitemap suggests that there is a blank line/space in your wp-config.php file or your theme’s functions.php file. I have checked your theme files but I could not identify this and thus the issue maybe on your wp-config.php file. Please check this files via FTP.
Looking forward to helping you. Thank you.
it seems it worked after i remove the blank from config.php. but the strange thing is i try to check rechanging for the previous one (with blank) and it continues to be ok.
