HTTP ERROR 500/500 JHtmlBehavior

[acdeuseonly]

Hi!I am having problems connecting to joomla administrator panel (HTTP ERROR 500), after the update from joomla 2.5 to joomla 3.5. And I was having another problem with site because of a database problem, so I restored a back of the site. But now not only the the administrator panel dont load (HTTP ERROR 500), the website gives this problem (500 JHtmlBehavior:: mootools not allowed). What should I do?

Oi! Estou tendo problemas para conectar-me ao painel do administrador joomla (HTTP ERROR 500), após a atualização de joomla 2.5 para joomla 3.5. Tive outro problema com o site por causa de um problema de banco de dados, então eu restaurei um backup do site. Mas agora, não apenas o painel do administrador não carrega (HTTP ERROR 500), o site dá esse problema (500 JHtmlBehavior :: mootools não permitido). O que devo fazer?

Hi, did you look at the error log on your server. Mostly 500 is an error in PHP, so you can try to find the exact error message in errorLog:

Try to enable debug mode in Joomla! - you should get more information about the problem - in which place it is displayed and why it is displayed.
