Most of the websites I build have a Hebrew frontend, this makes sense as the customer base of my clients speaks and reads Hebrew.
Wordpress supports i18n out of the box, most languages have their own customized install (including Hebrew) so that the websites starts in the required language right after install, if by chance you installed the "wrong" language, it is a quick matter to download the relevant language files and add support to the required language.
However this causes the ENTIRE website to display in the language of choice, including both the frontend AND the back-end, this poses a problem for some (like me) who like to operate in their working environment in English, this is because we are comfortable managing the site in English, this is what I do in this site, and in all sites I manage. This is for many reasons, not the least of which is the fact that all tutorials, plugin documentation and more are in English .when I look for them, translating them into Hebrew is a hassle in most cases, since clients can be taught to manage the site in English as well (and always like to save costs where it isn't necessary to invest in translation).
On this site, this is not a big deal, I run WMPL which allows me to translate any piece of content into as many languages as I want, and allows the admin dashboard to be in any supported language, regardless of what the front-end is displaying. However, this is a rather costly plugin (meaning it costs more the $0) and not everyone needs a multi-language site (for example I don’t, but I wanted to have one – because I can).
So for those sites on which I don’t have WPML installed I faced a slight problem, until I found this cute, simple and perfect plugin Admin in English which is free, and works exactly like I want it to, Turn the plugin on, the dashboard converts immediately into English, turn it off – it plops right back without any negative effect.
(a nice addition, which I might program into it, is setting the admin language by user – which would make it even more effective and useful.)
