Hello,
The issue still exist after I upgrade the theme to 8.2.4. If you want to reproduce the issue I met, simply follow my test procedure mentioned here
https://www.8theme.com/topic/server-stuck-after-open-several-customize-php-at-the-same-time/#post-277684
My customer keep asking me if the site is stable, I couldn’t response them, because this theme have the posibility to crash the server.
Any suggestion? thanks!
