When I try to add new sitemap in my admin panel I have this warning:
Warning: file_put_contents(/home/areavis/public_html/sitemap.xml): failed to open stream: Permission denied in /home/areavis/public_html/inc/classes/BxDolSiteMaps.php on line 138
Warning: Cannot modify header information - headers already sent by (output started at /home/areavis/public_html/inc/classes/BxDolSiteMaps.php:138) in /home/areavis/public_html/inc/admin_design.inc.php on line 48
How can I fix this? Please help
