TypeError: cannot concatenate 'str' and 'bool' objects

and i cannot access the update modules list because of this error.
document management folder is deleted and its components like 'search a file' is now in the main menu beside dashboard botton!!
how can i manually uninstall a module and solve my problem?
thanks
