Blank Administrator page after upgrade to Version 7.8.2

After recent upgrade to Version 7.8.2 started getting an empty page when selecting ‘admin’


Have you checked the apache error log? you can find the reason for the same.

Last line in log says:
PHP Fatal error: require_once(): Failed opening required ‘modules/OutboundEmailAccounts/OutboundEmailAccounts_sugar.php’
in …\modules\OutboundEmailAccounts\OutboundEmailAccounts.php on line 43, referer: …/suitecrm/index.php?action=DetailView&module=Users&record=1&type=&return_id=1

Thanks for your help!
