I recently moved my site to a different server and to save uploading times for the sql database, I emptied out all the cache tables. Now when I try to get the Popular links block to show, there is nothing in it. The log and summary pages all list everything as fine. I went through the code (don't know much, but enough to get by!) and noticed that for some reason the block uses votingapi_cache to get its records rather than votingapi_votes or pop_links_stats. Therefore I can only assume that since votingapi_cache was one of the tables I emptied to transfer everything over I have now lost the data needed for the block.
Is there any way I can get this back again, or have I lost everything completely?
