I need help: I installed variablecheck because I got some unserialize_... errors, and the report shows 2 bad variables - but it does not delete them. I check the boxes and click the "Löschen" (delete) button, but the stay. There is no error message from variablecheck.

Another thing about the upgrade procedure: The tmp directory must not be deleted, otherwise you cannot install modules.

Another thing about the variablecheck module: Newbies like me dont know where to execute it - it is in the "reports" section.

Sorry if I am off topic or if the question was already answererd, but the "search" funktion on drupal.org did not find it.

Thanks for any help,
Stefan
