I've got the same problem as described here (I read the thread):
I got the problem that I cannot change the message shown in the box. Even though I changed the message in the file:
Root/typo3conf/ext/cookieconsent2/Resources/Private/Language/de.locallang.xlf
(and yes, mine is a German website!)
Emptying the cache at Cache/Data/l10n/
as was suggested didn't work for me. Is there another solution?
Otherwise, I'll have to uninstall the extension, but it's hard to find something working for something as old as TYPO3 6.2 ...
Thanks in advance for your answer!
