Hey, I treid to create my own, first custom character sheet template via editor in game settings. When I saved, I got an error, unfortuanelly quite unspecific... So I tried to reduce my html, but still I got an error. In the end, I tried to save an empty custom sheet, still getting an error. Even in a newly created game with no players, nothing enabled. I tried to follow the guides given , e.g <a href="https://help.roll20.net/hc/en-us/articles/360037773373-Character-Sheet-Tips-and-Tricks#HowtoUseCharacterSheets-StartingaNewGame" rel="nofollow">https://help.roll20.net/hc/en-us/articles/360037773373-Character-Sheet-Tips-and-Tricks#HowtoUseCharacterSheets-StartingaNewGame</a> <a href="https://wiki.roll20.net/Building_Character_Sheets" rel="nofollow">https://wiki.roll20.net/Building_Character_Sheets</a> I cannot find any prerequisits I am missing. Is there a chance to see the details of the error without creating support ticket? (To debug my sheet) In the preview tab, the sheet I am testing shows fine. Test HTML code (no css, no translation) : < div class = "3colrow" > < div class = "col" > < label > Name: </ label >< input type = "text" name = "attr_Character_Name" /> </ div > < div class = "col" > < label > Geschlecht: </ label >< input type = "text" name = "attr_Geschlecht" /> </ div > < div class = "col" > < label > Rasse: </ label >< input type = "text" name = "attr_Rasse" /> </ div > </ div > < div class = "3colrow" > < div class = "col" > < label > Name: </ label >< input type = "text" name = "attr_Character_Name" /> </ div > < div class = "col" > < label > Geschlecht: </ label >< input type = "text" name = "attr_Geschlecht" /> </ div > < div class = "col" > < label > Rasse: </ label >< input type = "text" name = "attr_Rasse" /> </ div > </ div > Any ideas? Thx in advance for your help.
