Repository has not been enabled to accept revision propchanges; ask the administrator to create a pre-revprop-change hook

Not able to edit log message in your SVN?

Solution:

a). Go to your repository\hooks folder.

b). Create a file called "pre-revprop-change.bat".

c). Put the following contents into that file, and then save it.

rem Only allow log messages to be changed.
if “%4” == “svn:log” exit 0
echo Property ‘%4’ cannot be changed >&2
exit 1

d). Now, edit the SVN log message again. You should be able to edit the message now.
