## Symptoms

- * Either "`HTTP Error 500`" in Mobile Access Portal, or Mobile Access Portal fails to display.

* "`Access Refused`" with the normal portal layout is displayed when browsing to the full path for the login page.

* Debug of HTTPD daemon, while a connection is made to the Mobile Access Portal, shows the following error:

  `[error] [client `*X.X.X.X*`] PHP Fatal error: Uncaught exception 'Exception' with message 'Directory of /opt/CPcvpn-R77/log/trace_log/SSLVPNPortalLog.log does not exist!' in /opt/CPcvpn-R77/phpincs/logging/log4php/appenders/LoggerAppenderRollingFile.php:XXX\nStack trace:\n#0 /opt/CPcvpn-R77/phpincs/logging/log4php/appenders/LoggerAppenderFile.php(XXX): LoggerAppenderRollingFile->setFileName('/opt/CPcvpn-R77...')\n#1 [internal function]: LoggerAppenderFile->setFile('/opt/CPcvpn-R77...')\n#2 /opt/CPcvpn-R77/phpincs/logging/log4php/LoggerReflectionUtils.php(XXX): call_user_func(Array, '/opt/CPcvpn-R77...')\n#3 /opt/CPcvpn-R77/phpincs/logging/log4php/LoggerReflectionUtils.php(XXX): LoggerReflectionUtils->setProperty('file', '/opt/CPcvpn-R77...')\n#4 /opt/CPcvpn-R77/phpincs/logging/log4php/LoggerReflectionUtils.php(XXX): LoggerReflectionUtils->setProperties(Array, 'log4php.appende...')\n#5 /opt/CPcvpn-R77/phpincs/logging/log4php/configurators/LoggerConfiguratorIni.php(XXX): Logg in /opt/CPcvpn-R77/phpincs/logging/log4php/appenders/LoggerAppenderRollingFile.php on line XXX`

## Cause

Permissions are set incorrectly on the */opt/CPcvpn-R77* directory, or its sub-directories.

Another scenario possible: One of the core files in CVPNDIR is missing (could happen after upgrading or migrating) like trace_log.
