MediaWiki 500 Errors after install


MediaWiki works the first time you install it, but does not work after that, giving 500 errors.


It appears the version of the Zend Optimizer engine we have on our php5 servers now (3.0.2) causes problems with MediaWiki. To fix this, revert to an earlier version (3.0.1). Put the following in the php.ini file located in your MediaWiki install path: [Zend] zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.0.1 zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.0.1 zend_optimizer.version=3.0.1 zend_extension=/usr/local/Zend/lib/ zend_extension_ts=/usr/local/Zend/lib/
