Update on this if it helps narrow down anything...
So, I have leveled 5-50 so far with quester
Seems I only got the message when I was in the starter zones. I got it in Human starter zone and Night Elf starter zone. I have had zero reoccurring issues outside of the starting areas.

I agree with Better, it would take a lot of time to individually link each quest reward to specific classes to choose the best for each class/spec. I am currently running Jamba to help turn in and select rewards and Topfit to equip it. I am not sure how well it is working as it turns in and selects rewards at an incredible rate of speed. However it seems like I am getting more rewards that suit my class.

You will have to set both of these up specific to your toon for it it work correctly. Please take a few mins to look over the options in the addon (especially Jamba, it does quite a bit). 
Posted links are for 3.3.5 as OP requested, if you need a different version for your setup, navigate to your proper version and download.
Also Zygor Guides has an option to auto add your talents, just edit the ZygorGuidesBuilds.lua file if you want to create you own specific build. Super easy!

Agreed, a grind profile is really easy to make. If you need help on learning how to create profiles, let me know when you will be on chat and Ill come to help you.

I think i see the mistake. It is trying to conjure Item 8075 for food which is conjured sourdough bread. New toons need to update/add each conjured item. For new toons it should be item=1113/conjured-bread and 2288/conjured-fresh-water. That is for level 14. You will need to add each item you want to conjure for it to cast correctly.

A complete reinstall fixed the issue. Thought it might've been an issue with the fightclass I had made. Thanks for the help :)

Confirmed 

Big thanks, works like a charm.
