Uncaught SyntaxError: Invalid or unexpected token

I ran into a problem and I'm hoping a dev can help me out. I went into the dashboard of my wordpress site and then to widgets and noticed a problem. None of the drop downs or drag and drops work. I checked the console and found this error:

"Uncaught SyntaxError: Invalid or unexpected token load-scripts.php:343"

Here is a screenshot:

Here is the line of code for load-scripts.php:343 when clicked on

Here is a screenshot after I click on the error:

Not sure how to pursue this further. I've done all the turn off plugins and such to no avail. Any help would be appreciated fr this newb. Thanks.

回答1:

This is because an updated plugin is causing issue with some other part of WP that uses some javascript library.

Solution is to go to wp-config.php

And add this line

define('CONCATENATE_SCRIPTS', false);

This will tell WP to stop concatenating scripts, so you get all the JS you need.

I know this is an old topic (2 months) but I post this here as it might help somebody else finding this post via searches:

I have had the same or very similar errors with Wordpress, also on php7. Both other versions, and the latest (4.8.3 as of writing).

The solution has been very easy: I have just cleared the browser's cached files. Not cookies, just the cached files. That has fixed the issue for me.

I am not sure if it's the same issue as mentioned here, but that is to check.
