Switched client due to combat log bugs, now says 2 low lvl 2 use mount?

[Renn2017]

I just switched from warmane's client (warmane client runs better, but for me the combat log doesn't work well and addons like eavesdrop, pitbull and recount won't work) to hellfire's, changed the realmlist and copied over my warmane WTF to the hellfire folder.

It now says i cannot use my Gray Kodo until lvl 40..

What am i doing wrong?

Edit: I have played with the combat log fixer on and off, but it does not work either way.

My combat log always "bugged". He work around 5-6min after log in and then he ceases to show anything... SO, Recount and MikScrolling stopped work... Totaly annoying. Any idea how fix it?

I played while tbc on retail and you could only use mounts above level 40

It's patch 2.1, you can use mounts at 30
