File upload limit of 1MB in Roxy Fileman within Tiny MCE

In Nopcommerce 3.80: File uploads within the editor greater than 1mb do not succeed and no error is produced.



In nopcommerce 3.80 catalogsettings.fileuploadmaximumsizebytes no longer exists.

I cannot find any other settings in Admin/Setting/AllSettings


I am aware IIS has limitations but these are 4mb.
To eliminate this as a cause I have added the following to the web.config.

<system.web>
  <httpRuntime targetFramework="4.5.1" enableVersionHeader="false" maxRequestLength="10000" />
</system.web>
<system.webServer>
  <security>
    <requestFiltering>
        <requestLimits maxAllowedContentLength="1073741824" />
    </requestFiltering>
  </security>
</system.webServer>

Does anyone know where the upload size limit can be modified?

Same issue in 3.9. Just can't click on the uploaded, in our case, video file, to add it. Only option is to cancel or "x" out.

I am having same issue using 3.5 version.  What is the best solution to allow large file uploads using Roxy?
