The directory wasn't correct and I substituted the files as suggested, but now I get:

Warning: main(/home/aan75/public_html/Array/configuration.php) [function.main]: failed to open stream: No such file or directory in /home/aan75/public_html/components/com_comprofiler/plugin/user/plug_phpbbconnector/phpbbgui.php on line 39

Fatal error: main() [function.require]: Failed opening required '/home/aan75/public_html/Array/configuration.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/aan75/public_html/components/com_comprofiler/plugin/user/plug_phpbbconnector/phpbbgui.php on line 39

Array? I don't have a folder called Array in Joomla root!

Is it something to do with the Siteground shared hosting setup?

I'm having similar issues as well. Also using siteground.. If you solve that problem please post it here.
