Preview Post error

[ravenfaust]

When i preview a post it gives me an error: Warning: preg_match(): Compilation failed: invalid range in character class at offset 23 in ..../includes/class_wysiwygparser.php on line 481

And the words are all jumbled up,how can i fix this?

This is how I solved it. You can take it or leave it.

Line 481 includes/class_wysiwygparser.php


if (preg_match('#attachment\.php\?attachmentid=(\d+)# si', $img_url, $matches) AND preg_match('#class=(\'|"|)([a-z0-9_\-\s]+)?\s*previewthumb\s*([a-z0-9_\-\s]+)?(\\1)#si', $fullurl))



There was an unescaped hyphen and unescaped dot in the regular expressions.
