After updating MySQL 5.1 to version 5.5.x. I get an error when writing the article.

Warning: preg_match() [function.preg-match]: Compilation failed: invalid range in character class at offset 23 in [path]/includes/class_wysiwygparser.php on line 481

Please help.

find

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))

replace with

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))

You cannot possibly get that error from upgrading mysql, did you actually mean php 5.5 ?
