My hosting provider logs all PHP errors to a separate file. In a month I got a 7MB+ file filled with the following error message:
Unknown modifier 'p' in /wiki/includes/EditPage.php on line 1106
You can find my $wgSpamRegex from the LocalSettings.php on the following address: http://pastebin.com/EHH7fyDi
I copied it from a location you provided.
Version: 1.16.x
Severity: normal
It's a regex at fault/an error with the version of the PCRE libraries that your hosting provider is using
At a guess, it's "height:\s*[0-4]px", but it's valid regex...
It's an error in your regex:
"\<</span>\s*a\s*href|". //This blocks <a href links entirely, forcing wiki syntax
The regex is enclosed in /regex here/ , so the / in the span tag needs to be escaped, like so: \/span
Yes, you're right, I fixed that; thank you!
I don't remember from where I copied this snippet. I googled for it but I don't find to fix that.
