Hello to the forum users, I have a problem regarding a theme installation I had on Magento 2.
Being a bit of a layman with the platform, I wanted to ask for help from others to get a solution because I couldn't translate the error, since the administration panel works and the site keeps giving the security error, here is the problem log:
