In desperation, I removed Frontpage extensions and readded, but to no avail.
Now, the problem has gotten worse - I now can not upload anything. The error I get now, after entering correct login credentials is: Server Error: The server extensions were unable to access the file "frontpg.lck". Please check the file permissions.
I have, again, uninstalled and reinstalled Frontpage Server Extensions through Helm. Even clicked the "Check" option a few times, but to no avail.
Where do I go from here?
