[caesarizky]

Hi,

I'm having problem when generate report to Excel, after downloading the report file (excel), when opening the file on Excel it show error message like this :

<br />
<div class="errormessage">
<img class="errormessage" src="http://My_Web_Site/www/admin/assets//images/errormessage.gif" align="absmiddle">
<span class='tab-r'>PEAR Error</span>
<br />
<br />Using an input encoding requires PHP support for mb_convert_encoding() and mb_strlen()
<br /><pre></pre>

</div>
<br />
<br /><br />
<b>Fatal error</b>: Call to undefined function mb_convert_encoding() in <b>/home/.../public_html/opx/lib/pear/Spreadsheet/Excel/Writer/Worksheet.php</b> on line <b>1543</b><br />

What is the problem? i need help to fix this.

also on the Dashboard the statistic does not show correctly, in the box Community Statistic and Your Statistic only show an error message :

"Sorry, you cannot see this graph because the GD graphics extension is missing from your PHP installation.

Please contact your system administrator to have it installed. "

How to fix this problem?

Thank you

Have to enable "mb_convert_encoding" library function from php.ini file, or else have to install mb_convert_encoding [multibyte string library in PHP], this problem will get solve.
