No we are using linux the old and the new one was linux. Is it possible to fix theese files. Your hint is only working for new files. The strange thing ist that not every file with a special sign is broken. Only some. -----Ursprüngliche Nachricht----- Von: mediawiki-l-bounces(a)lists.wikimedia.org [mailto:mediawiki-l-bounces@lists.wikimedia.org] Im Auftrag von Robert Cummings Gesendet: Mittwoch, 23.

I know Windows causes this problem due to issues between the PHP engine, UTF-8 and Windows filenames. We use a JavaScript hook on the upload form to munge the filename so it contains plain characters only. Unfortunately I can't share it.

Oh my god the problem is fixed !!! :-) It was the APC Cache. We turned of caching and the site is working. Turning on cache -> site is not working. For me this is very strange APC is only a bytecodecache for PHP Files right? Thoose problems should never ever happen! Maybe someone open the files while it was not working and after we fixed the problem the cache still says the file is not there. Does someone know how to empty the apc cache?

Did you check if Zend Optimizer is disabled in the new server? APC is well-known to have show-stopper conflicts with Zend extensions. Regards, Usamah _______________________________________________ I use the standard apache of debian. If I look into a phpinfo there is a "Zend Memory Manager" enabled. Zend Extension is 220090626.
