    When i run my webgl game it loads the game but then shows a blank screen when loaded. when i load it again i get this message

    'An error occured running the Unity content on this page. See your browser's JavaScript console for more info. The error was:
    uncaught exception: out of memory'

    I have set my memory size to 512 and 750 and always get this mesage i have tried different optimization levels too and still get the same results. I have also tried less but then it tells me it is not enough. Any help you can give me will be greatly appreciated

    This isn't a clear cut issue. The browsers have to allocate the memory you set as one block. If you have not enough memory or the memory is very fragmented you will get the out of memory error even though the 500MB you set might be enough for your game to run.

    Starting on an empty browser and using a 64bit browser will help with this issue.

    Fixed it was a code issue. I added a condition within my code for webGL:

    Code (csharp):
    1.  Application.platform == RuntimePlatform.WebGLPlayer[/[code=CSharp]
    that got rid of the code issue

    @jimjim, so your script was causing a black screen only on web gl? Could you share what code exactly?

    the black screen was caused by us using a fadeout screen at the start of the game. the code then got stuck on a piece of code that did not exist in webgl build as it was looking for extenal function in the webplayer build that did not exist

    the if condition was used to stop the code being able to access scripts that did not exist in the webgl build, but did exist in the webplayer build. The problem i had was it was trying to access javascript code that was not part of the webgl build. The line was just implemented to only use this code for certain builds
