hi jack, got may admin/catalog back... can't really explain why, renamed the admin/.../english dir to german and that worked, then started checking the files, but couldn't find anything. copied the english categories.php to german dir and that worked, then merged old german to the english categories.php.... bingo!
now i have a new question: diid the HeaderTagsSEO test and got the following
HEADING_TITLE_TEST
TEXT_TEXT_INFORMATION
TEST_RESULTS_HEADING
ERROR_HEADING_EXTRA_FILE
ERROR_EXTRA_FILE
ERROR_HEADING_MISSING_CODE
ERROR_MISSING_CODE
ERROR_MISSING_CODE
ERROR_MISSING_CODE
ERROR_MISSING_CODE
wish I knew what is missing where...
