Title: Sharing – facebook problem Last modified: August 22, 2016 --- # Sharing – facebook problem * [Tomasz](https://wordpress.org/support/users/tpralat/) * (@tpralat) * [11 years, 7 months ago](https://wordpress.org/support/topic/sharing-facebook-problem/) * Hi, facebook is rejecting my wordpress site, claiming, its dangerous. I have done something with online security (McAffe online), but nothing changed. * Now, fb is saying: _“This link is blocked, or you have triggered an excessive amount of scrapes.”_ and _“Error Linting URL An internal error occurred while linting the URL.”_ * Another problem is jetpack comment system – it displays, but when I have ticked users must deliver email and name – it’s submitting and goes blank (even on admins acc). I’ve got standard theme with css modyfied and separated and __ in templates comments.php – but its not working anyway. * Debug is saying sth about headers too, but I found it too difficult to resolve even after many, many hours of seeking an answer. Can You help me with anything of above? * [http://travnik.net](http://travnik.net) [http://travnik.net/2014/10/18/tcwj-hummus/](http://travnik.net/2014/10/18/tcwj-hummus/)( for comments) Viewing 8 replies - 1 through 8 (of 8 total) * Moderator [Bet Hannon](https://wordpress.org/support/users/bethannon1/) * (@bethannon1) * [11 years, 7 months ago](https://wordpress.org/support/topic/sharing-facebook-problem/#post-5458146) * Your hummus images are making me hungry! 🙂 * Have you tried switching themes to one of the default WP themes, and seeing if FB will scrape your info then? * Looking at your site in an HTML markup validator shows some errors. While most of them should be derailing you, the last ones seem like they might be theme related. * Thread Starter [Tomasz](https://wordpress.org/support/users/tpralat/) * (@tpralat) * [11 years, 7 months ago](https://wordpress.org/support/topic/sharing-facebook-problem/#post-5458171) * I tryed once more, but changeing theme changed nothing for fb. And nothing for comments. I found [http://validator.w3.org/](http://validator.w3.org/) and tested travnik.net in html 5 and others, but do not know, how to repair it, I do not understand, how can I find paths to files and what is really wrong with them. All of lines looks like WP default – I did not changed them, so – is every WP install coming with such errors? I’ve tryed [http://galeria.travnik.net/](http://galeria.travnik.net/)( separate WP install) and found some too. * P.S. There is plenty of food on travnik, so be carefull what You are clicking, beeing hungry ; ) * Moderator [Bet Hannon](https://wordpress.org/support/users/bethannon1/) * (@bethannon1) * [11 years, 7 months ago](https://wordpress.org/support/topic/sharing-facebook-problem/#post-5458192) * After switching your theme, did the FB debugger show the new theme in it’s preview at the bottom, or the old one? Sometimes the caching takes a bit to catch up. Once, it took me 24 hours, and I couldn’t get FB to scrape new info that whole time! * I’m sorry, I don’t use Jetpack, so I can’t be of any help with the comments issue. * Thread Starter [Tomasz](https://wordpress.org/support/users/tpralat/) * (@tpralat) * [11 years, 7 months ago](https://wordpress.org/support/topic/sharing-facebook-problem/#post-5458193) * FB always says: “Document returned no data” when trying to see, how they see me. * Thread Starter [Tomasz](https://wordpress.org/support/users/tpralat/) * (@tpralat) * [11 years, 7 months ago](https://wordpress.org/support/topic/sharing-facebook-problem/#post-5458197) * 2 more things I found: 1. Commenting works fine, but only when I untick user must be registered and loged in to comment. 2. Carousel (jetpack) works only when in grid mode – slideshow makes gallery a standard WP slideshow in post. * Moderator [Bet Hannon](https://wordpress.org/support/users/bethannon1/) * (@bethannon1) * [11 years, 7 months ago](https://wordpress.org/support/topic/sharing-facebook-problem/#post-5458198) * For the Jetpack issues, please post on the Jetpack plugin support page: [https://wordpress.org/support/plugin/jetpack](https://wordpress.org/support/plugin/jetpack). They will be much better at offering support. * [Wilnesse Dericer](https://wordpress.org/support/users/wilnesse-dericer/) * (@wilnesse-dericer) * [11 years, 7 months ago](https://wordpress.org/support/topic/sharing-facebook-problem/#post-5458199) * I’m having the same problem here too. There must be a solution out there…. * Wilnesse Dericer * Thread Starter [Tomasz](https://wordpress.org/support/users/tpralat/) * (@tpralat) * [11 years, 7 months ago](https://wordpress.org/support/topic/sharing-facebook-problem/#post-5458201) * Theme Checker: * > **WARNING:** The flexible-width and fixed-width tags changed to fluid-layout > and fixed-layout tags in WordPress 3.8.
