There are about
5000 nodes in my website of different content types. After a while (updating the Drupal to
7.34 and configuring the Server by server administrator) some of node links are corrupted and they are redirected to the front page. They are not too many but I don't know why some links that were working, are not working now. As an example the link
/node/286 is redirected to the front page.
Is there any problem with the update that causes such thing?
The host server was victim of an attack and a few guest websites on it were hacked. So I guess (not sure!) the administrator may blocked some PHP functions, could this be the reason for such misbehavior of the links ? If it is right then why only a few of them are broken?
