[pmwiki-users] blocklist error

[adam overton]

hi y'all
has anyone ever gotten the following error:

preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 0 in /path/to/pmwiki/scripts/blocklist.php on line 172

it shows up on my edit page when i try and Save-and-Edit. the page still seems to save fine, but the message is worrying.

i'm running pmwiki-2.2.46 and haven't made any changes in awhile. i did add some new IP addresses to the blocklist recently and thought maybe that was the problem, but upon removing them the error message remains.

thoughts?
thanks,
adam
