There should not be any issue after changing this setting.Regards,
b) I have brought this to the attention of the developers, at the moment the setting will remain as it is.
c) There are no impacts on the front end that will affect the site.
After upgrading a 4.4 site to 5.4 some roles did not see the Pages next to dashboard.
Luckely I remembered that I had the problem before and was able to find this thread again.
Administration -> Settings -> Advanced -> Pages -> Sitemap filters ->Admin ->Parameters -> IsFrontendPageManagementFilteringEnabled
Must be set to False or uses will not see the Pages next to Dashboard.
I still have no clue what this setting does and why its true by default.
