Preg_Match(): compilation failed unknown property name

Question

I'm having a problem with a wordpress theme I bought but their support is terrible. On every post page, I receive this error:

Warning: preg_match(): Compilation failed: unknown property name after \P or \p at offset 7 in /nfs/c11/h03/mnt/206871/domains/ghldn.com/html/wp-content/themes/hive/inc/template-tags.php on line 230
data-first_letter="A">

I can see that the problem is in template_tags.php line 230, which is the following:

preg_match( '/[\p{Xan}]/u', $content, $results );

I can't see any problem there. What should I do?

Answer 1

Xan is a georgian letter as I can find in Google, but it's not a valid Unicode Script for RegEx, you can find a list of the Unicode Scripts here: http://www.regular-expressions.info/unicode.html

Maybe try using another one than Xan, maybe Georgian:

preg_match( '/[\p{Georgian}]/u', $content, $results );

Let me know how that goes.
