Anyone had any problems running the Memcached object-cache.php while using the Multi-DB plugin. For me it’s getting mixed up with requests and redirecting some sites to other ones, also not letting some people log in etc. Using WordPress’s inbuilt object cache seems to work fine so far, fingers crossed.
Note that Memcached is only supporting one instance of WordPress Multi-site over two servers, using Repcached to replicate Memcached data between servers. Never tested this before Multi-DB so no idea if it’s that or a problem with data not being unique enough in Memcached. If anyone has any similar problems or knows of a solution I would love to hear it!
