You seem to to misunderstand the "Plesk Repair Utility" a bit, I suppose. This tool is designed to investigate possible issues/errors/problems and misconfigurations and it will certainly NEVER break anything, it REPAIRS issues/errors/problems and misconfigurations to Plesk-standarts.and can here be come to troubles?
plesk repair fs
-n
-v
-y
Well... unfortunately, the Plesk Repair Utility can't repair all misconfigurations... but you should always consider to use it in the first place, which can save you a lot of time.So that is not the problem
ls -lah /var/log/fail2ban.log
a "work-around" is never meant to solve an issue, it should just make sure, that you don't suffer from a possible bug, which should be investigated by the Plesk developpers in order to be corrected!but this don't solve that problem
Where can i report bugs?
