No access to interfaces

[Andeh]

Well, after connecting the database to the CMS, I got errors.
Warning: require_once(app/interfaces/interface.core.php) [

You must be registered for see links

]: failed to open stream: No access to /opt/lampp/htdocs/global.php on line 27

Fatal error: require_once() [

You must be registered for see links

]: Failed opening required 'app/interfaces/interface.core.php' (include_path='.:/opt/lampp/lib/php') in /opt/lampp/htdocs/global.php on line 27

I tried removing that line to see if it was just that one, but it's all of the interface files.
I have no clue what the problem is, I'm using the latest release of RevCMS, on a Linux XAMPP server.

Check your folder/file permissions? It seems that they may not be readable?

Zeus, you need to make the opt folder writable by everyone.
opt/ isn't writable by default.

Had only done simple right click > preferences > permissions. CHMOD'ed and it works.
Thanks for the support.
