I haven’t installed any SP plugins.
I don’t know how to run an SQL script, so to save time and trouble just went in and removed all the duplicates. In 41 cases there were about 25 of each. In one case there was only one – “view_own_admin_posts” and its ID number suggests it was added almost at the end.
Following that you would then need to perform the ‘rest’ of all auths, rebuild those relationships in your forums and clear out the auth caches but that comes afterwards.
I don’t know what the above means or how to do it. Please give me specific instructions.
