Test Before Saving – Always returns error

Hello Webfactory and Alexandru, I’m trying to implement some header changes on my wordpress.com based site. I’ve noticed that no matter what I try, even if the box is blank, when I click ‘Test Before Saving’ the syntax editor tells me there’s an error. Here’s the code I actually want to enter: #Security Headers <IfModule mod_headers.c> Header always set X-Frame-Options "SAMEORIGIN" Header always set X-Permitted-Cross-Domain-Policies "none" Header always set Cross-Origin-Embedder-Policy "unsafe-none" Header always set Cross-Origin-Opener-Policy "same-origin" Header always set Cross-Origin-Resource-Policy "same-origin" Header always set Referrer-Policy "strict-origin-when-cross-origin" Header always set X-Content-Type-Options "nosniff" Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" Header always set Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline';" </IfModule> #End Security Headers Any idea why the editor is test failing? Would it be safe to continue with the above code regardless? Thanks, BB Hi, It’s hard to say… sometimes it can be a “false positive” where the update is OK but just the test is failing, but it’s risky. The test basically involves making the .htacces update and then making a request to homepage to see if it still works as expected. I guess in some cases there can be a firewall or some other issue that breaks the test. But like I said, don’t do it unless you have access to restore the .htaccess file FTP or your hosting panel.
