Hello,
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.
To determine that, please follow this troubleshooting guide:
https://rankmath.com/kb/check-plugin-conflicts/
Here is a video you can follow as well: https://www.youtube.com/watch?v=FcIWRhcUP2c
Only the site admin would know and your users won’t be affected by this troubleshooting.
If the issue persists, please edit the first post on this ticket and include your WordPress logins in the designated Sensitive Data section.
Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
https://wordpress.org/plugins/temporary-login-without-password/
You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):
https://wordpress.org/plugins/wp-security-audit-log/
Please do take a complete backup of your website before sharing the information with us.
We really look forward to helping you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hello,
I was able to replicate the issue on your site. I have forwarded this to our devs and will get back to you soon with an update.
We really appreciate your patience in the meantime.
Thanks.
Hello,
Could you please try a default .htaccess just temporarily to see if that helps fix the issue?
We are seeing that a lot of JavaScript files are not being properly loaded on the website and those could be bypassed by some rules inside the server rules file.
Here’s what a default one would look like:
# BEGIN WordPress
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
Looking forward to hearing back from you.
Hello,
I Just tried the default htacces. Nothing changed. Do i leave the htacces file as default or do i change it back to what it was.
Hello,
We found something that might be causing this and it’s related to the security software and firewall you have in place.
If you disable the Classic Editor and try to edit a post or page with the Gutenberg Editor you’ll see that a blank page is returned because the JavaScript execution seems to be blocked somewhere on the installation.
This is happening even if you disable Rank Math which means that there’s a fundamental issue loading JS files consistently.
Please check the log from the firewall/security software and make sure that there are no files being blocked from execution on the website.
Don’t hesitate to get in touch if you have any other questions.
Hello,

Thank you.
