Blog entry? Are you using a macro or a plugin? Please report issues w/ macros and plugins to theire respective maintainer.

You also forgot to report which version of Trac you're using: this is a very important info.

[ralf.peine@…]

The whole trac.db seems to be corrupt. Also admin isn't reachable by web browser. Is there any tool to check / repair the database?

Replying to ralf.peine@siemens.com:

The whole trac.db seems to be corrupt. Also admin isn't reachable by web browser. Is there any tool to check / repair the database?

From the log message, it rather looks like an invalid regular expression definition rather than a problem with the database.

Please try removing the blog plugin and make sure that the other parts of the system work without it. If that fixes the problem then the issue is in the plugin and needs to be reported to the plugin maintainer.

FYI (now it works well for me; just to tell u some situation..)

I added 2 WIKI entries with parentesis in the title, as follows: )bbbb (bbbb and the same problem happend, when accessing any wiki entry or any wiki entry list the following errormsg is shown (and it can't show the content of the entry or the list; wiki search result also yield the similiar result — )(AND after deleting the 2 wiki entries which cause problem, the trac system works fine)

It's probably because of the ​TH:AutoWikifyPlugin, and it looks like this problem has been fixed in ​[th 1925].
