I have build a page with the LWE and download it on the mmc of the controller. After when I went to try it from the net true the VPN the website seem as it was never downloaded. Could it be that the data-log file is erasing my LWE files to have more space to do the back-up, Can someone help me with this issue please? Thanks

The LWE Web-server project will be stored on the MSD card. Be sure your MSD card is a <=32GB card, formated according the LOGO! manual and LOGO accept the MSD card. Hope this helps
