Question

After install and successful configure (script returns no errors and all file permissions and ownerships seem to conform to documented guidelines), trying to access bin/view causes a 500 Internal Server Error. The httpd error_log contains lines like

[Tue May 09 14:09:07 2006] [error] [client XXX.XXX.XX.XXX] Unmatched [ in regex; marked by <-- HERE in m/(?-xism:[ <-- HERE \s\*?~^\$@%`/ at /home/httpd/twiki2/lib/TWiki.pm line 1226. [Tue May 09 14:09:07 2006] [error] [client XXX.XXX.XX.XXX] Premature end of script headers: view

Answer

Looks like you have the old NameFilter problem. Very strange, I was sure we had fixed that. Delete the line containing $TWiki::cfg{NameFilter} from lib/LocalSite.cfg.

Please double-check your TWiki version. Upgrade if pre 4.0.2.
