and after that the output (both Draft & Published) was blank. Even viewing it with a ?flush=1 attached to the url did not help. so i tried to undo the changes, but same result: blank page. Sorry, but these are my very first steps in SilverStripe and i do not even know wether my post occures in the correct place.
my Page.ss should be attached to this post, without the changei did, because as i said i undid that. And the change i did, did not touch any tags:i just had reclaced
At the moment i can not even reach the cms or the start page of silverstripe. all i get to see is a blank page. is there any way to get an error message out of it? if it helps: both the directories Includes and Layout are empty.
I took a quick look at the file and everything seems to be fine with it, but I think the problem is bigger than that. Could you have accidentally deleted some files?
As long as you're talking about the folders under mysite (and not under the theme you're using), I think it's ok that your Includes and Layout folder are empty (since it will pick up the layout from the template).
Either way, that shouldn't affect your being able to log into the CMS. What's your setup? Are you trying SS on a local machine? Can you reinstall? (what happens if you go to http://yoursite.com/dev/build/?flush=1 ... do you see anything?
