Edit Mode goes Blank in Chrome but working in other browsers


After login to Eidt Mode the page goes blank. nothing happened. I have read the help forums and most of the people suggested upgrade epi to fix it. Can anyone give me an alternative solution to fix it instead of upgrade. Thank you !

Hi Shan, when you say goes blank, do you mean that the left side navigation tree doesn't load (and maybe the other content in the "panels") but you kind of get the UI to loaded including top navigation? If this is the case you could try to reset your views by going to your logged in users settings (top right corner, click you user and my settings). In the view where you can set your preferred language there is also the button to reset views so click that and see if that fixes your issue (another temporary option might be to try the browser incognito mode and see if UI loads OK).

If it wasn't about that, open the developer tools and see if you get errors to console to help troubleshoot this issue.

When i say goes blank, that means nothing shows nor side panels nor anyother thing. Please check it <a ""> & with console window

Hi Shan, can you use some other image sharing service to post the pictures? domain popups as a source of malware source in google search. Paste your browser console log here so we can see the possible errors in plain text.

Hi Shan, have a look at this thread it has the same issue with the xstyle. So based on that the solution is hack or use othet browser or update UI.

Hi all,

Shan's my work colleague and we already found a solution. I'm just putting the solution here for other people's reference, especially for those who'll encounter the same problem.

Since an upgrade wasn't an option, we ended up just updating the js for xstyle.
Here's an article that discusses bug in detail and the workaround.

Inside the or, there are 2 files that you need to update

x.x.x.x is the version of the shell. Depending on your configuration, that shell item may be zip file or a folder.

Inside the .js file, search for the text "x-parse" and you'll see a code that looks something like this

Basically, the fix is the condition != normal needs to be added too.

So it should get updated to something like this

On some of our websites, updating just the widgets.js fixed the problem.
But on some, css.js needs to get updated to.

Hope this helps.
