Thread:Project:Support desk/Upgrade/migrate MediaWiki 1.12.0 to another server/reply (5)

So first off thanks a ton to all of you. Just got the move completed and everything is working great!

In case anyone is using the same system (SLES 11 fresh install) sometime, we had two errors come up which were fixed:

1) During the maintenance/update.php process - PHP Fatal error: Class 'DOMDocument' not found in /includes/cache/LocalisationCache.php on line 587 - This was fixed by using yast to install the following php modules: xphp53-dom, xphp53-xmlreader, xphp53-xmlrpc, xphp53-xmlwriter (Not all of these may be required, but they are what was installed)

2) After completing the update with no errors, the site would then return an internal server 500 error no matter what happened. HTML files would load fine. In Apache's error log we had various errors similar to this - PHP Notice: Use of undefined constant JSON_HEX_AMP - assumed 'JSON_HEX_AMP' in /includes/json/FormatJson.php on line 166 - This was fixed by then installing the php5-json module

Thanks again!
