Export to Excel no longer working

Hello. mygrid.toExcel stopped working. Export to PDF works fine. Can anyone help?

Show Grid <link rel="STYLESHEET" type="text/css"

Multi-Record Update

<th width="13" scope="col"><div align="left"></div></th>
<th width="176" scope="col"><div align="left">

please, describe mode in details how it doesn’t work - does any javascript error occur? does export script produce any errors in php logs?

Hi. I only see at the status area in browser “uploading…” then nothing downloads.

could you provide link to your grid page?
