OK, prfessional hosting is a whole different thing. Here in the forum we can help with most things LS related, especially for the community version. But when it comes to the professional hosting and the specifics I have no idea, as I am not part of Limesurvey GmbH, but rather do community support in my spare time.
So I don't know if you are even able to access those logs in the professional hosting. You should open a ticket under "contact us" to get support directly from Limesurvey GmbH, which is responsible for the professional hosting.
