i have a strange problem that occured recently. i changed my Header.ss - i put an hart coded link in and uploaded the file. at first glance everything seems ok, because the link apeared and i did not get any error message. now after two days i visited my page again i get this message:
Fatal error: Call to undefined method HttpRequest::addHeader() in /www/htdocs/xxx/xxx/xxx/sapphire/core/control/Director.php on line 115
i tried this to fix the error:
1.i uploaded "blackcandy" and changed the theme in mysite/_config.php. but it is still the same error in the frontend. (of course with /?flush=1 at the end)
2. .../?flush=1 - still the same error
3. ... /dev/build - still the same error (but i gues this is only possibel if iam loged in)
4. ... i overwrote Header.ss to the previouse version as it was working - still the same error
what is this? and how can i fix it. i am wondering if it would help to make an upgrade? because i am running 2.3.3 ....
could it be an cache problem? an where?
thank you for any help
