Update problem on v.

before a week i updated to latest version -
everything was ok, except during the update, .htaccess was replaced and the version of php used - different. So i restored it and finally update finished.
then i was using the application and before a day i opened it again and saw:

App update required

when i click “start update” - nothing happens.
i tried with occ update - again errors.
tried with php70, 71, 72

TypeError: Return value of OC\AppFramework\Http\Request::getScriptName() must be of the type string, null returned in …mycloud/lib/private/AppFramework/Http/Request.php:838

can i disable this update ? and how it decided that there should be an update by itself…

thanks !
