Hi, sorry for that really confused posting. More Details: After the Update from php4-4.3.4-43.44 to the new package (php4-4.3.4-43.46.3) "simulate static" in Typo3 doesnt work anymore. I choosed this list because it was a security update. The php.ini changed, without .rpm backup, but use of the old one do no change. According to the Apache Logs [Tue Nov 29 13:07:02 2005] [notice] child pid 16499 exit signal Segmentation fault (11) somewhat breaks (most likely the PHP Engine if i use a Link like http://www.meinziegelhaus.de/cms/Ihr_Ziegelhaus.7.0.html So the Link dont react and Apache gives the above Error Message - this happens only with this Links so it seems to be a Problem with the Variables or the handling of them? So the simpelst Questions are: How can i change back to the older PHP Version? (Thats the really urgent one) Whats wrong with this Update and why cant i find any Update logs for this? tia, Michael
