Not able to modify records from database
I have just installed a FileMaker Server version 220.127.116.110 on MacMini OS X Version 10.9.5.
I use three databases which have identical settings in regards to Accounts privileges/extended privileges, Sharing and Log-in settings (File Options > Login using [un-checked]).
There are four user accounts in each database who can access in full level.
Two of the databases I am able to modify (edit fields, add or delete records). The third database I can access, however it can not be modified. The New Record and Delete Record are grey-shaded and other functions are not permitted (duplicated record etc). I noticed also that the specific database although it has the same size as the other two, in file length, loads much faster (almost instantly).
All users have the same issue: Two databases working fine, they can not edit/modify the third one.
I am not sure if this is relevant but I also get this message from the server:
Client "Vi El (VL's MacBook Pro) [XX.XXX.XXX.XX]" authentication failed on database "FILEMAKER 2015.fmp12" using "Vi El [fmapp]".
I am new with FileMaker Server and trying to figure out this issue. Thank you in advance for any help with this.
