dokuwiki problem

[Stefan Bellon <sbellon@sbellon.de>]

Hi!

I am using Debian unstable and have set up a dokuwiki and it worked very
well in the past. But since a recent update, I get the following errors
displayed in the browser window after changing and saving a page:



Warning: preg_match() [function.preg-match]: Compilation failed:
repeated subpattern is too long at offset 14466
in /usr/share/dokuwiki/inc/common.php on line 391

Warning: preg_match() [function.preg-match]: Compilation failed:
repeated subpattern is too long at offset 17093
in /usr/share/dokuwiki/inc/common.php on line 391

...

Warning: Cannot modify header information - headers already sent by
(output started at /usr/share/dokuwiki/inc/common.php:391)
in /usr/share/dokuwiki/inc/actions.php on line 106



When I reload the page, I get the same displayed again, but with an "A
newer version exists, Save or Cancel?" at the bottom of the page. Even
if I Cancel, the changes have been submitted. Nevertheless this is
completely irritating for the Wiki users.

Anybody any idea?

Thanks in advance for any hints!
