@Kovid,
I did a new installation with the actual version and made a new source clone.
Did you change something with custom column build from other columns? I have with the actual version 2.99.8 template errors in all custom columns with functions and program mode. I haven't check this before but see it now in the GUI library. Do I need to change something in the templates?
Start manually the server and the server is running w/o problems except the custom columns issues.
Debug log: caldebug_RunNormal.txt (in Zip)
Running from source:
I start w/o automaticly starting the server. Same as above. Then I start manually the server and get this error
Why in progam files directory? My CALIBRE_DEVELOP_FROM is "c:\Users\Armin\git\calibre\src\"
The debug log do not show this information but shows of course the other errors with custom columns above
Debug log: caldebug_RunFsource.txt
Last source code change was from 16:48:43 this afternoon ("Also scroll window to zero on content load").
