Hi all I’ve coded a small shop that works well on my dev machine (OSX 10.5). But look at the following page: [http://shop.incense.ch/compact\_discs/1](http://shop.incense.ch/compact_discs/1) When clicking “Reservieren”, the page is forwarded to a new page, where the product is added to the shopping cart, and a flash notice is prepare. Then the page is redirected back to the shop page. On my dev machine this works well. But on the production server this doesn’t seem to work! But look what happens when you click on another link, e.g. “Kontakt”! There the stuff seems to be! What the heck? Never stumbled over this before… Anyone has an idea what’s wrong here? Thanks Josh ---

Hi Josh, could you post some source code (of “add” action for example) and some more info about your production env? Do you display flash messages in your layout or view files? If in view files, do you include it on the page where it is missing? Best, Hubert On 28 Pa¼, 19:07, Joshua M. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

I just created a new app on the server using the tools that are available, and there with a simple people-scaffold flashes etc. seem to work without any problem… ---

I did a tail -f log/production.log and watched the log while clicking on the “Reservieren” Button.

Yes, it’s definitely a caching problem. In production mode the whole page is cached, so it is loaded from public/compact\_discs/xxx and so the flash is not displayed. What a newbie mistake… 🙂 Thanks anyway for help. ---
