Mod Rewrite Rules / .htaccess

I must be missing something obvious, but I can't figure out why this isn't working:

This is my complete .htaccess file.
RewriteEngine On
RewriteRule ^tags/([A-Za-z0-9]+)/?$ tags.php?tag=$1
RewriteRule ^tag/([A-Za-z0-9]+)/?$ tags.php?tag=$1
RewriteRule ^blogs/([A-Z0-9]+)/?$ archive.php?lid=$1

The 3rd and 4th lines work. A visitor to domain.com/tag/reviews will be shown the correct content generated by tags.php. But a visitor to domain.com/tags/reviews will be shown only "No input file specified." which comes from Apache, I think.

(This is on an Apache server running PHP, of course.)

Can any one explain why the 2nd line doesn't work? Thanks in advance!

 

Looks like a typo.

 

Both the 2nd and 3rd line are supposed to go tags.php - the same file. I added the 3rd line to try to figure out why the 2nd line wasn't working.

 

Have you tried flipping the order of the rules, to see if it makes any difference?

Alas, swapping lines 2 and 3 makes no difference.

 

Have you checked your error logs to see if anything shows there? Apache may have logged a more specific error.

Also, this Google search:

google.co.uk/search?hl=en&safe=off&q=mod_rewrite+%22no+input+file+specified%22&btnG=Search&meta=

(I can't post live links yet, sorry about that)

May help you.

Try removing the ? before the $ at teh end of the match string, i've never seen them before, but i think ? affects the Mod_Rewrite engine. If it needs to be there, try placing a \ before it.
