If you get the above error when you access TRAC, it means that you do not have:
View existing wiki pages [WIKI_VIEW]
permission on the TRAC instance. Speak to your administrator about granting you this permission via a role.
For your TRAC Roles, at a minimum, you should grant the following permissions to an user to avoid the WIKI_VIEW privileges error:
- Can access Trac
- Trac -> Wiki -> View existing wiki pages [WIKI_VIEW]
Therefore, either add the above permissions to an existing Trac Role, or create a new Trac Role with the above permissions
