Index.php added to my URLs since migration to Cloud

Hey,
Since cern.ch/wlcg-public was moved to Cloud, I found:

  1. all my automatic URL aliases ceased to work and they reverted to default (I have to re-save the URL alias pattern then “update URL aliases” in the Content screen)
  2. index.php has been added to all my URL aliases.

I can’t see index.php anywhere via the edit or configuration screens. See screenshot. Here, my mouse is hovered over “Tiers” link in the menu; you can see the target bottom left. This is the case for all the menu links.

Then, equally, when I want to login, I cannot as index.php added to the URL aliases invalidates the login. I eventually got round this by deleting index.php from the alias, but it shouldn’t be there in the first place.

Help please!

Thanks,
Cath
