My site is loading very slow since I installed plugin W3 Total Cache, and when I do a test at pingdom it seems that some parts of the WPML plugin are causing problems. Is there some advice about the use of both plugins together please? thanks in advance!

I've been looking around here and found in a topic that it could be a problem with the object caching, so I disabled the object caching and loading time is much faster... is there a bug somewhere?

You're right. Object caching in W3TC doesn't allow WPML to set the language information for objects. As a result, the cache gets continuously overwritten by different languages.

If you disable object caching, W3TC will work great with WPML. We're aware of this and are planning to work with W3TC team to fix.

thanks for help guys, I hope there will be a solution got the object caching with W3TC combined with WPML, until then no object caching 😉

Any update on this? Would really speed up sites if we could use object caching properly.
