0Fixação editor visual wordpress

Eu tive um problema recentemente onde o editor visual wordpress parou de funcionar. A multa editor de código trabalhou, mas o botão visuais simplesmente não fazer nada. Eu sabia que não era uma definição de servidor, pois impactada 2 de 5 sites WordPress no servidor, mas os outros funcionou bem. Eu tentei apagar e copiando cópias novas de “wp-includes” e “wp-admin” em caso de algo tinha começado corrompido, mas isso não resolver o problema, quer.

I also tried cre­at­ing a new user, which loaded with the visu­al edit­or activ­ated. No entanto, as soon as I switched to the text edit­or I got stuck and could­n’t switch back.
I tried dis­abling all plu­gins, and chan­ging theme, Mas nenhuma dessas ajudou, although this might be due to extens­ive use of cach­ing on the live site.
Even­tu­ally I found a sug­ges­tion on WPGuru to add a set­ting to wp-config.php which did the trick.
define('CONCATENATE_SCRIPTS', false);
This sug­gests that one of the scripts on the 2 affected sites isn’t oper­at­ing cor­rectly so I will try to track this down. The strange this is that it can­’t be a built-in script because I re-copied the wp-admin and wp-includes folders, but it also should­n’t be a theme or plu­gin as I switched to a default theme and dis­abled all plu­gins! Muito estranho!
When I have time I will invest­ig­ate fur­ther to pin­point the prob­lem script and will update this post accord­ingly. My best guess at the moment is that it is hid­ing in the wp-con­tent dir­ect­ory struc­ture somewhere
