I just noticed that my game recently compiled in HTML5 refused to start on my Apache server.
I compared the new "index.html" file with the old one and replaced "createFolder" by "createPath" in line 60 and 70.
After that my games are starting OK.
I'm using version 5.09
Was that an attempt to solve the problem of thumbnail staying black while saving (assigning .png picture on the "Savegame screenshot" property makes no change)?
Should I update to a newer version, and if yes, is there a procedure to be able to come back to my current version?
