Question Google detected crawling due to authorization

[3dpoder]

Google detected a significant increase in the number of URLs we were blocked from crawling due to authorization permission errors.
Recommended action 
Check the Crawl Errors  page in Webmaster Tools.
Check if your server or host is blocking Googlebot.
If you don't want Google to crawl these pages, consider adding them to your robots.txt .

When I visit these pages blocked the result is this:

Warning: preg_match() [function.preg-match]: Compilation failed: missing ) at offset 102 in /home/poder/public_html/foro3d.com/dbtech/dbseo/includes/url/check.php on line 165

This is working as intended, and you want this to happen. This way, Google won't try to crawl areas you have closed off to guests, causing your publicly accessible content to appear higher on the search rankings.
