Hi
After switching to PHP 5.4.4 , we started receiving this weird errors in admin upon saving a product. The product is actually updated, but I guess I see this error when the redirect to category.php is done. Log says:

PHP Fatal error: 1065:Query was empty :: in ***/includes/classes/db/mysql/query_factory.php on line 120

We're using Zencart 1.5.1 on PHP 5.4.4 and MySQL 5.5.33.

We are using database caching only in front end (no caching in admin, where this actually happens) and I see that this fix is already applied:

https://github.com/zencart/zencart/c...4f845ca345f247

but I guess it doesn't matter much as when I switch to file based caching in front we keep receiving this error (in admin).

We have lots of mods installed, lots of our own modifications as well, but all worked before and now suddenly we started getting this in admin. I noticed that I get this error in one more area - when I try to send a gift certificate mail via admin. I've read and tried all that I could find in the forum but with no result.

Any help or debug hints will be appreciated!
