Thread:Project:Support desk/Mass disappearance of pages in mediawiki upgrade/reply

Hi!

The PHP notices are not relevant for you; you could change the error reporting settings of PHP, if you do no longer want to see them.

Upgrading in one step (instead of in different steps) should be fine.

Some extensions are currently still missing, e.g. the tag is not rendered currently. However, the page, that you linked to, does contain some content and I can also see it and the pages linked on that page. For which pages do you have problems?
