I have a problem with a PHP script. The following error is being logged whenever the site is accessed:
[Fri Sep 26 11:57:56 2014] [error] [client 31.22.44.2]
PHP Fatal error: require_once(): Failed opening required
'./sites/default/modules/views/handlers/views_handler_field_markup.inc'
(include_path='.:/usr/share/php:/usr/share/pear') in
/var/www/www.xoomtalk.com/htdocs/sites/default/modules/views/includes/handlers.inc
on line 76
I have confirmed that the file referenced is present, and that www-data can access it. Permissions look fine and have not been changed as far as I am aware
What am I missing?
I managed to solve this problem, ended up being nothing to do with permissions or paths, although there was no indication of this in the Apache logs.
The problem was that the server was also running AppArmor which for some reason was blocking the Apache process from accessing the files.
AppArmor was set to complain rather than enforce mode for testing (command is aa-complain apache2) this made everything start working.
Thanks to all contributors for their suggestions.
