 * Dear Support,
 * I have tried to modify this page, but when I want to save it I get this error:
 * “Something has prevented this page from being saved. Please make sure you are
   at least an Editor and have the unfiltered_html capability.”
 * Of course I am the editor, I am the admin of the page.
 * I have a simple “Thank you for your registration” page, which I can modify and
   save as normal.
 * I am on Firefox developer edition and Win11. WordPress 6.9.4, all the plugins
   are updated.
 * Thank you for your help.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcannot-save-modifications%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hello,
 * Thanks again for contacting us!
 * We usually find this particular issue is to be related to an active firewall 
   setting that seems to be blocking the saving process. This usually happens when
   it picks up Javascript code within the page’s HTML content while saving, also
   preventing the preview from being generated.
 * If you’re currently using Wordfence, you may temporarily activate Wordfence’s
   learning mode, save the page, then re-activate its standard protection mode. 
   This should essentially mark any Javascript data in the SeedProd page being blocked
   as safe.
 * [https://www.wordfence.com/help/firewall/learning-mode/](https://www.wordfence.com/help/firewall/learning-mode/)
 * If you have any other firewall plugin or server-side firewall service active 
   on the site, you may contact their support team to help unblock and permanently
   allow pages to be saved in SeedProd. They’ll be best able to help locate this
   blocking event and add the correct rule to allow this process.
   Disabling plugins
   one by one can also help identify and mitigate the issue.
 * Best regards,
