[pmwiki-users] Websites not working - something to do with ResolvePageName()?

Sorry for the delay.
At first I couldn't find a problematic line, but now I suspect this one:
"/[^[:alnum:]_-\\s]+/" => '' # remove non-alnums
Try writing it like this:
"/[^[:alnum:]_\\s-]+/" => '' # remove non-alnums
(move the dash character right before the closing bracket)
The dash inside a character class, except when it is at the beginning or
at the end, defines a range between characters (actually codepoints),
eg. a-z meaning all characters between a (97) and z (122).
On that line, you have _-\\s where \\s is any whitespace character
(space, tab, line feed, form feed, carriage return), and the dash is not
at the end.
If you changed nothing, I suspect something changed in the PHP
installation so that a previously working pattern stopped working.
