Because the $100 for the plugin itself is for the work that went into creating the plugin :)

vBulletin / Internet Brands charge you $170 for a Branding Free licence for your forum.
vBSEO charges you $117.

Having branding increases traffic to our site, driving sales and helps us to provide even more awesome products.

Even if 1 in every 10k visitors to your site is actually a forum owner themselves (either in the present or in the future) and would be interested in our products, that's still 1 lost sale.
If we then assume that your site gets 100k visitors, that's 10 lost sales.

10 lost vB Optimise sales equates to $1000, which when compared to a $100 Branding Free licence is actually a pretty bad business deal for us :)

Hopefully that makes it clearer why we put branding in our mods, and why we charge such a high fee to remove it :)

Enabled debugging and noticed these errors

First of all, those aren't errors, they're just incorrect API calls that vB silently discarded.

Secondly, they're not related to vB Optimise, as I don't believe that mod ever fetches forum permissions at all :)

What is the affect on server memory when caching? I run a big board with a unique situation that I am trying to solve without spending a bizillion a month on hosting. In a nut shell most of the time I have 300 - 400 users online and they make 3200 - 4000 post a day. 13 days a year I have around 600 - 800 online and for about 5 hours they make about 2000 post a hour. This is causing my memory to fill up while the processor is processing the request.

I doubt vB Optimise will help you with memory usage - in fact, most opcode cachers are designed to steal MORE memory in order to avoid hitting the CPU for re-running PHP scripts.

You might be best off getting a Memcache server on a separate machine, and also stuff your MySQL on that second server :)

Would this mod be necessary if your using nginx?

Does the lite version not support caching templates from guests?
i dont undestand this.

Nginx doesn't deal with opcode caching so yeah, it still has an effect :)

Guest caching is a Pro-only feature :)

When i run test it gives one error which is

That means your chosen opcache operator isn't working correctly as it's unable to store data - you should contact your host :)
