Text Editor Missing

[.m.]

as it is a premium theme, I'd suggest to contact theme coder and ask if the theme is converted to MyBB 1.8.x

almost all templates of the theme need updating to have full advantage of MyBB 1.8.x new features

Visit your Admin Control Panel, then go to Templates & Style > Templates > Find Updated Templates. This will show you a list of all the templates that have changed during the upgrade.

You can either revert these templates to their default - meaning all the changes you've made to it will be removed - or you can see a Diff Report which will show you exactly what's changed. If you have a custom theme installed, it is probably best that you look at the Diff Report and apply the changes you need.

temporarily, you may install a good looking new theme compatible for MyBB 1.8.x and use it
