Thread:Project:Support desk/Upgrade from 1.15.2 to 1.23.0 with section errors/reply (9)

So a summary of what we have:

Your old MediaWiki 1.15 works fine on PHP 5.2.x. It does not matter, if you upgrade MediaWiki to a newer version or not: As soon as you use PHP 5.3 or newer you do no longer have content on some pages.

Contradict me, if I am wrong: These broken pages always are the same ones and they are still working correctly in PHP 5.2.
