[TYPO3-english] require_once error after uninstalling extension

[Joakim Hansen]

Installed YAG, it failed. Backend started to give errors. I deleted typo3temp/Cache/*

Using Typo3 6.1.7.

Now I'm getting this error when I access the page at /typo3/index.php:

Warning: require_once(/myweb/typo3conf/ext/yag/Classes/Utility/Flexform/Div.php): failed to open stream: No such file or directory in /myweb/typo3temp/Cache/Code/cache_core/ext_localconf_39e3b98d508aca2997a9bb35822a72ea66f75cf3.php on line 1475
