I've updated a 6.20 site to 7.0 I've seen no errors during the update.
Strangely, a lot of comments are now empty. That is: The title, author and date are correct, but the comment content is not there anymore. It's not a theme issue: I've tested with garland. Additionally I'm receiving this error in dblog
Warning: array_flip() [function.array-flip]: Can only flip STRING and INTEGER values! in DrupalDefaultEntityController->cacheGet() (line 354 of /var/www/zona7/includes/entity.inc).
But the error appear also when I visit a page without comments, it seems to be unrelated.
If I create a new comment, there content is there.
In what table of the database is the content comment? (I've checked the 'comment' table and I found the title of the comments, but not the content)
Please, report if you have seen this behavior or write a comment if you can help me somehow, thanks
