I was experimenting with caching a website. (That’s absolutely new to me…) I did some updates on the site templates and disabled caching in the config.php. I emptied the cachefolder but after reactivating caching I got a white screen… If I disable caching I still have a white screen… 
Anyone an idea how to get my site back?
Have you turned on debugging in config.php? Can you find an error in the server log files?
Yes, but I don’t get any error messages. I Still have a white page.
Might be an error in the template you edited. Or in the config file.
Yep, I found it. And it had nothing to do with the caching… unfortunately activating the cache and updating the template was in the same deploy…
