 +=== Can't import virtual machine due to existing uuid ===
 +
 +If you have multiple webhmi images in Virtual box, you can encounter this error, becuase virtual image being added usually build based on previous one, so it may have the same uuid for itself or vdi files. For this, you can detect 
 +which machine has colliding uuid with the VBoxManage command line tool and in the virtual storage manager in Virutal Box. 
 +
 +===== Visualization issues =====
 +
 +==== Dashboard editor ====
 +=== SVG image is not displayed during editing ===
 +
 +The SVG file should have "width" and "height" attributes in the header. Otherwise it may hide while editing in some browsers, like FireFox, see the below picture:
 +
 +{{ network:svg_img_resp_bug.png?direct&600 |}}
 +
 +Please reset the "responsive" property in your svg files. 
 +
 +==== Orphaned images ====
 +=== Image choosing popup in dashboard editor has orphaned images ===
 +
 +If you accidentally deleted some images or folders with images directly from SD card - pass the /setup/images/list.php**?orphaned** parameter to url. System now will read list from databse (not directly from SD card), where deleted records still exists. Make the relevant changes to syncronize your records with really-exists images.
 +Feature available since version 4.1.3.7945
