Help: My WordPress posts won’t display – Increasing the Backtrack Limit

You just spent an hour writing up a new lengthy post for your WordPress blog that explains the migration habits of monarch butterflies in great detail, and finally hit publish.

You take a look at the post to see how it looks, but what’s that? It wont show! What’s happening? Is my site getting hacked? Maybe, but before you jump to that conclusion, try this solution on for size.

The problem could be a PHP limitation on the number of backtracks allowed. So as new posts are added, they just don’t get loaded if the number of characters is longer than the default setting of one hundred thousand.

Open your favorite PHP editor, and take a look at wp-config.php ( If you don’t know what that means, it might be best to have someone do it for you . . . )

Take a look at the line that reads (you may have to add the line with the other ini_set’s):

ini_set(‘pcre.backtrack_limit’, 100000);

and change the number to something large like 4,294,967,296 (This is the limitation in most databases):

ini_set(‘pcre.backtrack_limit’, 4294967296);

Apparently it’s a known issue that WordPress has yet to correct. I guess it doesn’t occur often enough for them to worry about it.

    Then we wouldn’t have Colorado, Chicago or other chaos.Black men make them wiouhtt marriage. White men are starting to do that as well. But white men also make them IN marriage and then leave the family and make a new family and forget about the other children from the previous marriage, two, three and four times. Yes, I am saying it. Women can’t raise boys to be men. WIthout men raising men, the next generation will have none.What is happening in the USA? Waiting for the irresponsible men to start making excuses.
