Modifying Texts in Toolbar

Hello everyone,

My forum version is ModernBB and forum langugage is Turkish. I recently wanted to open the toolbar but as it seems some of the wording is not translated to Turkish, it stays as English. So, I was looking for a solution to change the phrases.

I've came across this topic which is precisely what I want to do, change translations and maybe change some words all together.

But I can't make it work on my main forum. I tried it on a different forum and it works there, (ModernBB and language is English)
So it must be because my forum is in Turkish.

@Ange Tuteur I thought I should tag you as it looks like it's your coding. Hope it's okay.

Okay, after days of trying, found out the reason.. My bad. Turns out script was clashing with another one, cause the same letter was defined as the variable. The code I linked above works as it should be, for future reference.
