Ok, just installed sitemap wordpess plugin and activated it but its giving error Could not write into /home/my_name/public_html/health-center/sitemap.xml Could not write into /home/my_name/public_html/health-center/sitemap.xml.gz Code (markup):
did you chmod the appropriate files & directories? you can do this via FTP or SSH/putty. on most FTPs you can select the files/folders, right click, and there should be a chmod property. from the shell it'd be something like chmod -R 777 /the/directory/ -R means recursive, and anything inside "directory" will be chmodded to 777.
depends on your hosting situation... you could chmod the files individually if you prefer, or do something like chmod -R 777 /the/directory/* that would only match all the files in the directory and not chmod the directory itself
