Problem with ZMSSqlDb [2 Attachments]

Hello group,

i got a problem regarding the ZMS-Object "ZMSSqlDb" and blobs (newest version of ZMS 2.13.0c1.1314 ). 
The MySQL-databaseconnection is okay and working. But the blobfields in ZMS seems to have a problem to read the saved files. 
In the configurationtab of the "SQL-Datenquelle" i configured the tablecolumn as a blob and insert a local path on the harddrive (see picture).
Inserting a file works fine and it is stored in the folder on the harddrive. But when you edit this object you see the error (see picture2) "InternalError". Its seems that the server can't read the uploaded file.
This website worked fine on older version of ZMS (ex. 2.10.4). So is this a error in the newer version or did i something wrong?


best regards
Boris Kaminski
