DMS Editor is not loading. I have tried using different browsers and also have cleared my browser cache, but still no luck. 
Please find screenshotattached. 
Thanks in advance! 

Hello - I'm a registered Pagelines user. I tried to load my website today (toolshed.biz) in the DMS editor and received a message that the page was having trouble loading. I rarely make changes to my website so this was unexpected. I followed your support suggestions and checked for javascript errors using Chrome - when trying to load the page, it showed the following
jquery-migrate.min.js:2 JQMIGRATE: Migrate is installed, version 1.4.1
pl.editor.js?ver=16e8ee:740 Uncaught TypeError: Cannot read property 'lang' of undefined
    at Object.reloadConfig (pl.editor.js?ver=16e8ee:740)

    at chrome-extension://kamiaabbnpncbobdiblhfogafnoefkae/contentscript.js:38:28
I deactivated all my plug-ins prior to doing this except for:
Pagelines Platform 5 v5.0.126
Pagelines updater v. 1.2.9
I'm not an expert coder or web developer, not really sure what this all means. Not sure what JQMIGRATE is (a plug-in? I don't see that in my plug-in list). Can you point me in the right direction?
Thanks,
Dick Huey

Hi, the DMS editor is not loading on landing page. It is working on all other pages. How do I fix this? the website is selborneproperties.com I have logged in and logged out, have disabled plugins. Thanks,
David

Greetings
Was on the phone with client yesterday reviewing the site and the server slowed way down. Did a couple updates that may not have taken. Now cannot get back into the DMS editor for http://cassclayton.com/dev/  I can see the site in chrome and firefox but the background image is no longer there. Can get into dashboard in chrome and firefox. Cannot get into DMS editor in chrome - get "Oops, There may be an issue loading." error no matter how many times I try.  My internet connection is not the fastest, but I can access other sites I've built in DMS - just not http://cassclayton.com/dev/
My question is,
1) is there a safe way to reinstall DMS that will not trash the work done on the site? 
2) Is there a way to see if something in the database got corrupted and how to fix? Since I can't get into DMS editor, can't get to the Flush Cache page to try that.
Just turned on
define('WP_DEBUG', true);
Help!
Thanks

My DMS editor isn't working on my landing page, all other pages can be edited using the DMS editor. 
Is there a fix for this???
