Hello,
I duplicated my site to make a dev site, and that site when CacheApc is turned on changes the product stock correctly when altered through the backoffice. The original site however doesn't, when you change the stock with CacheApc the stock won't update (only in the database).
In my app/config/parameters.php I have the same secret/cookie keys etc only the database is different, everything else is identical.
What is the problem?!
