Error reporting Need help solving joomla display errors Joomla or server errors?

Var $error_reporting
reporting level and display_errors 'none' or 0: disables error reporting entirely (in error log and in web browser) 'simple': enables display_errors, displays only E_ERROR, E_WARNING and E_PARSE 'maximum': enables display_errors, displays messages from https://www.joomlart.com/tutorials/joomla-tutorials/joomla-error-reporting-explained E_ALL category 'development': enables display_errors, displays all error messages (-1, since php 5.4 this is the same as 'maximum') Numeric value: enables display_errors, value is passed raw to error_reporting() so it expects the same format Usually, 'default' is the most reasonable choice. 'none' is a bad idea because it disables logging the errors. Session handler The session handler variable controls where sessions are stored - http://massivescale.net/article-joomla-configuration-php.html that is, where data about logged in users are kept. Every value but 'none' and 'database' requires a PHP extension installed. 'none': Let PHP handle saving sessions according to its save_handler and save_path variables. Most often it stores sessions as files in save_path. 'database': Uses the database to store sessions. Requires no extra PHP extensions. 'apc': Uses the Alternative PHP Cache to store sessions in RAM. 'memcached': Uses the Memcached server to store sessions in RAM. Requires the memcached PHP extension. The server is configured like this: public $memcache_persist = '0'; public $memcache_compress = '0'; public $memcache_server_host = '127.0.0.1'; public $memcache_server_port = '11211'; 'memcache': Uses the Memcached server to store sessions in RAM. Requires the memcache PHP extension. Using this extension is not recommended, 'memcached' is better. The memcached server configuration for Joomla 2.5+ is identical to the 'memcached' option above. For Joomla 1.5, the configuration looks as following: var $memcache_settings = array('compression' => 0, 'persistent' => 0, 'servers' => array(array('host' => '127.0.0.1', 'port' => 11211))); 'wincache': This is only available on Windows servers (it's an oxymoron if you ask me). 'xcache': This uses the excellent XCache PHP extension to store sessions in RAM 'xcache'

One way to learn from errors is to establish a reporting system. Reporting systems have the potential to serve two important functions. They can hold providers accountable joomla error log for performance or, alternatively, they can provide information that leads to improved safety. Conceptually, these purposes are not incompatible, but in reality, they can prove difficult to satisfy simultaneously.Reporting systems whose primary purpose is to hold providers accountable are "mandatory reporting systems." Reporting focuses on errors associated with serious injuries or death. Most mandatory reporting systems are operated by state regulatory programs that have the authority to investigate specific cases and issue penalties or fines for wrong-doing. These systems serve three purposes. First, they provide the public with a minimum level of protection by assuring that the most serious errors are reported and investigated and appropriate follow-up action is taken. Second, they provide an incentive to health care organizations to improve patient safety in order to avoid the potential penalties and public exposure. Third, they require all health care organizations to make some level of investment in patient safety, thus creating a more level playing field. While safety experts recognize that Page 87 S
