Good morning,

I am an administrator of several Moodle platforms, in versions 3.1. I have installed on each of the Moodle platforms the mathematical editors plugins of wiris (for Atto and for tinyMCE) version 4.5.0.1372.

I went to the wiris filter information page, http: // <moodle> /filter/wiris/info.php and everything appears OK without error messages.

The problem comes because several users are complaining that they can not generate the mathematical formulas using the Wiris editor. You open the window where you can create the equation, but at the time of giving the "Accept" button to generate and display it, this button does not take any action.

I have made several tests on my computer, with several browsers, and in my case, I correctly generated the formulas without any problem. Could the versions of the browsers that are being used have anything to do with it?

Thank you very much
