I want to disable the cache and went to basic settings -\> Frontend cache… but it doesn’t show the form to edit settings and instead pops up this error ` Oops! An error has occurred! The following notes should help you.

Hallo, to solve the problem you need to have a look at the database. Please check the table s\_core\_config\_values if there is an entry for value like "%s:326:„fronten%“ and delete this value. Afterwards check the basic settings again. Moritz
