Overcompensation is a method often used to get over little hitches like this.
Here's a trick that might help
point your front arm in front of you where you want to go. By pointing your arm to your toeside, your body weight will shift enough to force your front toe down, if you are following the other advice above.
This (using your upper body to affect your foot pressure) is very bad technique and once you get the feeling of your toeside transition again you should focus on refining your turns and using proper pressure and weight distribution through your turn cycles.
If you are getting to your toes but the tail rotates too far and you end up catching your heel edge, make sure you are pressuring the back toe edge after the apex of your turn in order to maintain your turn degree.
The opposite issue was addressed above. Also, don't use your front foot as a pivot and swing the tail of your board, initiate your turns with the front of your board as described above.
Also, going slow and focusing on connecting turns might help.
