I posted earlier my issue on wrong thread in the forum. I rebuild my web site to use WordPress as CMS (Content management system). I removed old WordPress and removed all files under 'public_html" folder before I install new version of WordPress on main folder 'public_html'
However Google XML SiteMap plugin that I just installed can't generate SiteMap. I try to repeat whole process to re-install WordPress and plugin but didn't help. I try to change permission of folder 'public_html' to 755 and didn't help. If I change permission to 777, my web site show message 'Internal Server Error'
What should I do next?
Thanks in advance
