Answer 1

1) Look the var/log for errors.

2) Try to reindex with SSH like this :

Individual re-indexing:

php shell/indexer.php --reindex catalog_category_flat

php shell/indexer.php --reindex catalog_category_product

php shell/indexer.php --reindex catalogsearch_fulltext

All re-indexing:

 php -f shell/indexer.php reindexall

Then clear the magento cache.

Answer 2

1) Look the var/locks for any locks is there.

2) Remove all the locks files (*.locks)

3) Try to reindex with SSH from the Magento root like this:

php -f shell/indexer.php reindexall

Then clear the magento cache.
