Hi Gergo!
Thank you for your answer! I've now enable that option. I modified the htacess before to make it work with
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
</IfModule>
I don't consider the default editor as a wysiwyg one since I got some issue with it, I though your plugin could overwrite the default one with CKeditor or another one for example. My bad!
If you find a way to do it tho i would gladly appreciate it since I can't make the plugin "Wysiwyg Editor" and "CKEditor" works for me. Maybe an idea for a futur update?
Best regards!
