I have a subdomain working on Joomla without any problems. Suddenly, when you click on any item menu in the subdomain, you will get the message: Warning: fopen(/home/filetwod/public_html/movies/administrator/components/com_sh404sef/logs/[login to view URL]) [[login to view URL]]: failed to open stream: Permission denied in /home/filetwod/public_html/movies/components/com_sh404sef/[login to view URL] on line 118 Array ( [0] => option [1] => coming-soon-in-lebanon [2] => ) 500 - SH404SEF : headers were already sent when I got control! Killed at line 444 in [login to view URL]: HEADERS ALREADY SENT (200) URL=[login to view URL] OPTION= the subdomain is [login to view URL] can you fix this issue?
