Fatal exception of type MWException
Solution 1
As written in the comments, edit your LocalSettings.php
file and add this line at the very end:
$wgShowExceptionDetails = true;
Try reloading the page that gives you that error. You're likely to see what's called a backtrace... here is my example:
#0 /Users/user/www/extensions/LocalisationUpdate/LocalisationUpdate.class.php(553): LocalisationUpdate::filename('it')
#1 /Users/user/www/extensions/LocalisationUpdate/LocalisationUpdate.class.php(36): LocalisationUpdate::readFile('it')
#2 [internal function]: LocalisationUpdate::onRecache(Object(LocalisationCache), 'it', Array)
#3 /Users/user/www/includes/Hooks.php(255): call_user_func_array('LocalisationUpd...', Array)
#4 /Users/user/www/includes/GlobalFunctions.php(3883): Hooks::run('LocalisationCac...', Array)
#5 /Users/user/www/includes/cache/LocalisationCache.php(796): wfRunHooks('LocalisationCac...', Array)
#6 /Users/user/www/includes/cache/LocalisationCache.php(426): LocalisationCache->recache('it')
#7 /Users/user/www/includes/cache/LocalisationCache.php(310): LocalisationCache->initLanguage('it')
#8 /Users/user/www/includes/cache/LocalisationCache.php(245): LocalisationCache->loadItem('it', 'fallback')
#9 /Users/user/www/languages/Language.php(3978): LocalisationCache->getItem('it', 'fallback')
#10 /Users/user/www/languages/Language.php(230): Language::getFallbacksFor('it')
#11 /Users/user/www/languages/Language.php(189): Language::newFromCode('it')
#12 /Users/user/www/includes/Setup.php(497): Language::factory('it')
#13 /Users/user/www/includes/WebStart.php(161): require_once('/Users/user/3d...')
#14 /Users/user/www/index.php(55): require('/Users/user/3d...')
#15 {main}
The first line is the one that stopped the execution, causing the exception. If you can identify the problem (in my case it's the LocalisationUpdate extension) it can be very easy to fix. Again, in my case it's enough to open again LocalSettings.php
and comment out or delete the line:
require_once( "$IP/extensions/LocalisationUpdate/LocalisationUpdate.php" );
Solution 2
There could be a problem with caching, try to use
$wgMainCacheType = CACHE_NONE;

$wgShowExceptionDetails
Enable more details (like a stack trace) to be shown on the "Fatal error" page." We would need to know more than just "Fatal exception of type MWException".
