    Hello,

    After migrating the website from a local development environment to online development environment I get the white screen of death when I try to edit a post or page. The serverlog gives me the following error:

    Error 35.189.242.143 [client 35.189.242.143] ModSecurity: [file "/etc/httpd/conf/modsecurity.d/rules/tortix/modsec/50_plesk_basic_asl_rules.conf"] [line "301"] [id "340149"] [rev "152"] [msg "Protected by Atomicorp.com Basic Non-Realtime WAF Rules: Potential Cross Site Scripting Attack"] [data "ecmascript"] [severity "CRITICAL"] Access denied with code 403 (phase 2).

    I’ve deactivated the other plugins add the problems still persists.

    Plugins I’m using:

    • Advanced Custom Fields
    • Contact Form 7
    • Imsanity
    • Gutenberg

    Any idea what cause of this problem is?

  • Can’t help but I have the same problem!

    I have found the solutions. The server firewall blocked the file because it contained code the firewall deemed suspicious: “Potential Cross Site Scripting Attack”. Ive whitelisted the error ID and now the file is served.
