It seems that you are directly making changes inside the installation.You should not do this.Ideally you should create a maven project and should make the changes.
Below can be issues if you still want to make the changes in installation.
<config replace="true"> <flags> <!-- Developer debugging setting to turn on DEBUG mode for client scripts in the browser --> <client-debug>true</client-debug> <!-- LOGGING can always be toggled at runtime when in DEBUG mode (Ctrl, Ctrl, Shift, Shift). This flag automatically activates logging on page load. --> <client-debug-autologging>true</client-debug-autologging> </flags> </config>
