One more question, I followed what was indicated in the red warning
Note the big red warning says this:
Only for SME Server 9 64 bit which is now EOL and deprecated.If you are using Koozali SME v10 then it is not SME v9 so
DO NOT USE THAT PAGE. You may well trash your server and need a restore to get it back to normal.
If you are using v10 then your Horde version is 5.2.23
If you are still using v9 then you must upgrade immediately. We do not offer support for outdated versions beyond upgrading it to v10.
