Permalinks Plugin Fails

On wordpress 3.9.1 and php 5.5.9

So for a while the custom permalinks was causing the entire pages page to fail to load. I fixed this by changing the part of the code with the mysql_real_escape_string, and i was able to alter the pages again.

However, now I an unable to change any links at all without getting a 404 on the link i just created, with one exception. On one site i used “PHP on pages” and i was able to add the PHP extension to all of my pages, but I still could not name them anything else.

For instance, I cannot do website/blog because it fails entirely. Basically, I cannot make any permalinks whatsoever which do not return 404’s. The only links that work on this particular site are the .php links, but on other sites I work on the permalinks still fail completely.

Also, i have mode reqwrite enabled.

Any help with this problem would be appreciated.
