Occ error after update 14

  1. The database is missing some indexes. Due to the fact that adding indexes on big tables could take some time they were not added automatically. By running “occ db:add-missing-indices” those missing indexes could be added manually while the instance keeps running. Once the indexes are added queries to those tables are usually much faster.

 Missing index “share_with_index” in table “oc_share”.
 Missing index “parent_index” in table “oc_share”.
 Missing index “fs_mtime” in table “oc_filecache”.

2. The “Referrer-Policy” HTTP header is not set to “no-referrer”, “no-referrer-when-downgrade”, “strict-origin” or “strict-origin-when-cross-origin”. This can leak referer information.

i guess this could be solved by this thread (haven’t tried it yet, though)
