Troubleshooting

Professional hosting services often disable certain features from their servers for higher security. If you have the access to make one of the previous changes, and you have followed the directions fully, but it still doesn't work, you should check with your host to see what restrictions you need to work under.

Some of the previous improvements, especially the PHP add-ons, are not compatible with one another. If you are having trouble with a new change, try disabling any other nonstandard settings first and see if your new change will work alone. If it does, you can add back your other optimizations one by one to determine exactly where the conflict lies.
