I am not sure whey you are refering to TinyMCE, i dont think thats the editor that magento setup in its 18.104.22.168 version. never the less, I disabled the default editor and the problem is still remaining. As mentioned before I used your theme on a brand new magento 22.214.171.124 installation with almost no addons. This problem should not be there. I wonder if other people have the same problem with this installation. Nevertheless, please advice me to how to fix it.
