WHMCS tinymce html editor issue

[SpeedySRV]

Hello,

I am having trouble using the tinymce HTML option when creating articles, email templates, etc. Pretty much, anywhere there's a WYSIWYG text-editor and it has the option to switch to HTML mode, it does not load anything in the window that comes up. I noticed in the dev tools with Chrome, it returns the following error when loaded:

 

Blocked a frame with origin "https://mydomain.com/" from accessing a frame with origin "null".  The frame requesting access has a protocol of "https", the frame being accessed has a protocol of "data". Protocols must match.

Refused to display 'https://mydomain.com/clients/assets/js/tiny_mce/themes/advanced/source_editor.htm' in a frame because it set 'X-Frame-Options' to 'deny'.

 

I did have HEADER always set X-FRAME-Options SAMEORIGIN in my httpd.conf but since I noticed this, I removed it and restarted Apache and still have no luck. I am currently running my website with WHMCS on a LAMP stack. The only other thing I could think of is my uBlock origin ad blocking tool but that's disabled and my website is whitelisted. The only other changes I've made to my Apache config file were:

 

# Prevent File ETag Attacks
#
FileETag None

# Disable TRACE Request
#
TraceEnable off

# X-XSS Protection
#
Header set X-XSS-Protection "1; mode=block"

 

Any idea how I can fix this?

Thanks!

Hi,

Are you able to provide any more information with your issue?

What browser are you using?

I can see that @SpeedySRV is using an SSL, does your system also have an SSL @ITWolfy?

What version of WHMCS do you use, what version of PHP are you running?

As much information as you can provide would be helpful.

Hi Andrew thank you kindly for your time taken to help me.

I Use Vivaldi Browser, but tests on Firefox & Chrome are the same blank popup.

I Do use SSL yes.

Version of WHMCS is latest 7-4-1

PHP is 5.6

Switching from TinyMCE to CKEditor with a plugin I installed after having trouble with TinyMCE is a work around but not a solve for my problem.

I appreciate your time taken to help us with this problem.

I have fixed the issue by getting rid of uBlock origin Chrome addon. Now I'm facing the issue as twolfy.
