Hi all,

My first post here :)

I have problem with that message after clearing all cache in backend, after another refresh everything is ok, but this is vey annoying. Our site is multi domain, and this new one is based on fluid, other ones are flux. 

Is there any help for this, some recomendations? Do you guys any more info?

Thank you in advance.
