My Holystica multi sites ALWAYS looses the permalink structure!
and whenever i do an upgrade of some plugins the permalink strucutre of each sub blog is gone and i get a 404 not found error.
then i just have to go inside the dashboard of each sub site > to the settings -> permalinks ... select default -> save
then change subsite and manually repeate this action again and click save again and all is fine again :wink:
but it is really sort of annoying to loose the permalink structure after EVERY upgrade. Can you help me? Do you have any solution? I can pay for this solution...
