You might come across errors like the following during a Sugar CRM installation:-
PHP Warning: require_once(modules/Administration/UpgradeHistory.php) [<a href='function.require-once'>function.require-once</a>]: failed to open stream: No such file or directory in /home/<username>/public_html/crm/install/install_utils.php on line 48
[Sun Jan 04 22:44:43 2009] [error] [client 61.95.196.73] PHP Fatal error: require_once() [<a href='function.require'>function.require</a>]: Failed opening required ‘modules/Administration/UpgradeHistory.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/<username>/public_html/crm/install/install_utils.php on line 48
This can be fixed by giving necessary permission for directory /home/<username>/public_html/crm/modules and for the directories inside. I gave 777 for the directories which appeared in the error message and the installation completed like a charm!. Like in this case you will need to do the following to fix it :-
chmod 777 /home/<username>/public_html/crm/modules
chmod 777 /home/<username>/public_html/crm/modules/Administration
Hope this helps all Sugar newbies
