TYPO3 Core

In case someone encounters the same Indexed Search problem:
That was easy to solve by making the path of the form action absolut.

This of course does not help with the Extension Manager problem

I can confirm the problem with extension manager on 6.1.4. The requested url when clicking on gear icon that should open extension settings is:

http://domain.com/typo3/mod.php?M=tools_ExtensionmanagerExtensionmanager

shouldn't it leads to some controller/action and points some extension?

I have just upgraded sources to the latest git version (6.1.5-dev) through git clone and symlinked them. After clearing configuration cache / all cache i can access exension settings without any problems.

So this seems to work with 6.1.5-dev. Not sure though if it was related to sources or some cached configuration/content.

I would be nice to know which file of the source made it work again.

Andrea i don't see any change since 6.1.4 release that can have any influance on EM (see: https://github.com/TYPO3/TYPO3.CMS/commits/TYPO3_6-1) so maybe you should try to empty all typo3temp/ dir, clear configuration cache and than all cache. See if this will help on 6.1.4

Thanks - Patch set 2 linked in #51767 solved the issue.
