Image rating doesn't work

[mawenzi]

... I made some modifications in the last days on my Website ...
... and now my problem : image rating doesn't work ...
... I restored some backups of the modifyed files ... but ...
... the rating form works well ... the page reloaded ... but than ... nothing ... no message, no voting, no saved rating ... 

... now my question for restoring backups ...
... which files are involved for a image rating ... ?
1. page_header.php --- Save Rating ---  (no changes in this time)
2. sessions.php ---> $session_info  (no changes in this time)
3. functions.php ?  (some changes in this time)
4. details.php ?  (some changes in this time)
5. details.html ?  (some changes in this time)
6. rate_form.html  (no changes in this time)
... still other files ?

... has someone an / another idea to solve that problem ... ?

Thanks for the assistance ... mawenzi

1) Are your votes saved in the database? or you are using the default type with cookies?
2) did you check the categories permissions, maybe somehow voting is not allowed?
3) even though you say page_header.php was not changed recently, still try to use "Save Rating" code block from a fresh 4images. I should not break your site, but atleast you should be able to determin if the problem is somewhere in that block or in functions.php
4) you can try to debug, starting with functions.php
There is update_image_rating() function that update the rating. Try add echo $image_id." - ".$rating; in it see if it shows the correct image id and the rating when voted.

Good luck.
