Call to undefined function removeDir when deleting a document

[Daniel]

I tried to delete a document and get the following message:

Fatal error: Call to undefined function removeDir() in /volume1/web/docu/LetoDMS_Core/Core/inc.FileUtils.php on line 113

The entry for the document goes in fact away but after the deletion the folder view shows the following error:

Fatal error: Call to a member function getVersion() on a non-object in /volume1/web/docu/out/out.ViewFolder.php on line 118

I can remove the above error when i going to delete the entry for the document within the database table tblDocuments.

Other functions of LetoDMS are not affected.

I'm using LetoDMS 3.2.2.

Any idea?
