From the live chat -
Seems like there is a conflict somewhere in the system, when I checked the console error, could notice the following error:
'jQuery is not defined’
I have added the following code inside your sites wp-config.php file:
This has loaded your WP dashboard without any issue.
However, just to be sure whether any plugin is causing the issue, you'll have to disable all the plugins in your dashboard, and then temporarily remove the above code added inside the wp-config.php to see the issue still exists.
If the issue is doesn't exists, the you'll have to enable the plugins one-by-one, and see which one breaks the dashboard again. If it's a live site, would recommend you to perform this in a staging site. :)
Other than that, the above code inside wp-config.php should be good.
Problem resolved and I am SO happy!
Thank you so much!
I assume this is a pretty serious situation. I am feeling very nervous because the site has been down over 24 hours at this point. Any updates on what is going on or a possible restoration time?
