What does the log say the problem is?

how can I find error in log file?


I have created a html link to check log file error, because I did not understand it.



To find an error in a log file, read it!

A quick scan of that log shows there are two big errors, but it is possible that the first error is causing the second.

The second error is something wrong with reading/writing the database, but you need to fix the first error before looking at this one.

The first error is "unable to clean plugin cache".  This is usually caused by the directory or its contents having the wrong permissions. 

You need to check that the whole of the Jira home directory is owned by the user that runs the Jira service and it has full access to it.  Because of the poor design of Windows, we sometimes find virus scanners block access to Jira files and directories, so make sure these are off.



Thanks for reply.


But I have checked that there is full permission to user and owner.  I have already tried to delete indexes folder from cache.  New index folder also created into this, I also have given full permission to everyone to check, but still same problem.

You need to work out why the process cannot access that directory.

Try logging in as the user (not yourself or an admin) and deleting files (after taking a copy).  You should be told why the OS is stopping you
