some previously working .htaccess 301 redirects are no longer working...

Also, a newly added redirect is not working.

I have no idea when they stopped working, just noticed it today.

Below are examples. The first one I tried to add both in the .htaccess file itself, and then using the cpanel utility. No luck either way. The second one used to work, but doesn't now. And the third one still works. I cut and pasted all of these from the same .htaccess file, so something odd is going on.

redirect 301 /fitness/fitportal/group/Daily%20Tips/ http://www.JeremyMarkum.com/fitness/fitportal/group/Articles/

redirect 301 /fitness/innercircle/index http://www.JeremyMarkum.com/fitness/fitportal/index

redirect 301 /fitness/fitportal/full-entry/how-to-stretch-your-groin-before-you-train-legs http://www.JeremyMarkum.com/fitness/fitportal/full-entry-exercise/how-to-stretch-your-groin-properly-before-a-workout

Suggestions? I could really use some help here.

301 php redirect? Mine took a couple mins to set up.
