Could you be more precise? When does this error happen exactly? Can you login at least?

Maybe you could install XDEBUG on your server so that the error comes with a nice stack trace that we could track?

Thanks!

Correction: it breaks for all installs on the same server and it works for some installs on another server.

It happens when I log in: I get a blank page (error_reporting is set to false) instead of the backend and I get the line I gave in php error log.

Could check particular environment information on this server, so that we can narrow down the search?

- OS?
- PHP version?
- Webserver Version and used SAPI (FastCGI? Apache Module? ISAPI?)
- Loaded PHP modules (APC? eAccelerator? Zend? Xcache? Others?)

Thanks for your help!

The behavior is very strange. I thought it worked for a site after an apache reload so I extended the 4.5.1 to other sites. I logged in and got a message in the backend: no module found, try to reload.
I reloaded the backend then got wrong page icons in the page tree and got recently updated docs when clicking on cache menu.
I'm back again on 4.5.0.

I use firefox 3.6.13, I tried to switch to private navigation and it seems to work for all the sites. When back to normal navigation it works. Seeing the PHP error log, I would'nt have thought of a browser cache problem but it seems it was.

Yeah, everything related to "ExtDirect" might be affected by wrong Javascript or information in your browser's cache. Can you confirm that it works fine after clearing the browser cache even in "normal mode" in Firefox now?

Well, after testing on 6 sites on this server, everything seems to work fine now, even in normal mode.
I don't remember if I've cleared the browser cache! just remember having switched to private navigation then went back to normal.

Thanks for the feedback. So it was a client issue. Anyway strange problem, and we will keep that in mind.
