Ok it works as root, but this is not expected behaviour. The user owns the whole .wg++ dir.
What permission is missing?

By the way. Why is this a hidden directory starting with "."?

just a guess but did u chmod +x webgrab exe?
it needs write permission for robot.txt files,ect

very strange results.
usually i would say its a ini or webgrab exe problem but you said it works when run as root which makes me think its a permission problem but u seem to have checked all that already.

Are you running as user or root ? Also update to 3.2.2.5 https://github.com/SilentButeo2/webgrabplus-siteinipack/blob/master/eval...

Yes, does it need any file outside its own directory?
Has mono some restrictions in network access or anything?

As user it crashes, when I run it as root it works.

Same result with V3.2.2.5

let's start from beginning...
change config as here https://github.com/SilentButeo2/webgrabplus-siteinipack/blob/master/site...
add your license line user + password and add channels.
delete your license files under /root/.local/share/WebGrab+Plus/License/*
Then run as root and set in config update (see update mode license line in sample config)
then it should work.

Of course I can run mono. And it works with other exes

Ok I have this file ~/.local/share/WebGrab+Plus/License/wglocal.lic for root but not for my user, only the directory, which is owned by me.

No it does NOT help copying the license file.

i meant remove .lic from that folder.....then run update f in license line...

I don't understand. I think I should rather avoid updating the license file ... but how.

I have no wg user name. As root it works nevertheless.

It doesn't matter what I set for license or if I remove the file, it crashes anyway.

you cant.
license update is not performed every run,its every so many days(something like 14 i think)
wg checks the date in the lic.log file to see if its needs to be done.

.wg++ is drwxr-xr-x and owned by me
It does not have to be in my home dir, right?

out of sugestions but it definetly seems to be a permission problem somewhere.
did u try giving the user admin(or root) permission just to see if it will run the same as it does as root user.

user is in wheel and operator group.
+s for mono wouldn't change anything

I can even update it from a linux vm which has the same user and mounted it via nfs.

your config looks fine,i assume in your license like u removed "To force a license update; replace this text with the letter f"
and replaced it with f(to force a update,dont leave it as f).either blank is fine after a lic. update.
either way this will not cause a crash as it still works as root.
it must b something to do with bsd file system.
u said u checked all permissions but anyone other that root(i assume) has permission problems it seems.

just to test i run webgrab on my nas(its fedore based firmware not bsd) and am usually signed in as root.
i created a user with no root permission and ssh to my server and it ran fine as the user.

you should have it under your user home mine is /home/ubuntu/.local/share/WebGrab+Plus/License where ubuntu is the user, delete the .lic files, because old version like 3.1 are not compatible with new license system. Then do a force run see if it appears, it should work.
