<div> </div>
<div>this seems to be an issue that we fixed already long time ago. I think in 2.6 or in 2.7.</div>
<div>This error happens if you create a spreadsheet as a child of a workbook and we fail to load</div>
<div>this structure properly in the older releases.</div>
<div> </div>
<div>As a workaround, just create a "stand-alone" spreadsheet without using the workbook.</div>
<div> </div>
<div>As a permanent and more preferred solution, please update to the last release 2.8.1.</div>
<div>A lot of work and many improvements were done after 2.5 and I'd really recommend you</div>
<div>to use the most recent version of LabPlot.</div>
<div> </div>
<div>Please check the recent blog posts on labplot.kde.org if you want to get an overview of</div>
<div>what was changed after 2.5.</div>
<div> </div>
<div>Best Regards,</div>

<div>P.S.: writing from a web-interface, sorry for the potentially broken formatting...</div></div></body></html>
