Hi Wendell,

I have backed up and deleted the unneeded entries from mlf_entries. However, I don't see any way to associate the mlf_entries_cache with the main entries.

Don’t worry, it’s too late. They should have had identical ids.

Would it be safe to simply delete all entries from mlf_entries_cache? Would it regenerate the cache on its own or would I be breaking the site?

In my understanding [sic] the former. The scripts should look up whether an entry with the same id already exists in mlf_entries_cache, and – if not – generate a new entry with rendered HTML. Untested (I don’t run mlf 2.x). Suggestion: Delete one entry of the cache table in the database, call the post in the forum, and check whether a new entry is generated.

[…] Since I really just wanted a record that I could look back on when needed […], I simply exported the entries I didn't need online anymore as a backup. No need really to move them into another table.

Sounds reasonable.
